る。According to the fishing rod A according to the present embodiment, the strength and the rigidity are the same as those of the conventional fishing rod, and the fibers such as the glass fiber, the carbon fiber, and the armide fiber that constitute the fishing rod body 1 are impregnated with the matrix resin such as the epoxy resin. The outer layer reinforcement formed by the woven cloth 15 made of PEI (polyetherimide) fiber, which is a fiber of high elasticity and high strength, is developed by a tubular body made of a cured product of the prepreg sheet 10 and has impact resistance, tone and feeling of use. It is expressed by the layer 3, the forehead reinforcement layer 6 and the inner reinforcement layer 9. Since this PEI (polyetherimide) fiber has toughness and elongation, it has extremely high impact strength. Therefore, for example, even if a shock is given or a stone is hit, it is hard to break and is not easily scratched. Also, PE
Since I (polyether imide) fiber has good wettability,
The resin is easy to turn during processing and has good moldability. Therefore, the coating film thickness can be reduced and the weight can be reduced. Further, since the PEI (polyetherimide) fiber has a high elongation rate of the fiber, it is hard to be broken against deformation and has a smooth swinging tone, and does not bing like a conventional fishing rod.
又、小口５には、小口補強層６が埋設されているから、
小口５の割け，割れ，欠け等が防止出来る。Further, since the forehead reinforcing layer 6 is embedded in the forehead 5,
It is possible to prevent cracking, cracking, chipping, etc. of the small edge 5.
更に、元部７の内壁面８には、内層補強層９が埋設され
ているから、次節との当たりによるササクレ，割れが防
止出来る。Furthermore, since the inner reinforcing layer 9 is embedded in the inner wall surface 8 of the base portion 7, it is possible to prevent a crack and a crack due to the contact with the next section.
更に又、この釣竿Ａでは、ノイズが吸収緩和されるた
め、魚の当たりのみ感知し易くなる。Furthermore, since noise is absorbed and relaxed in this fishing rod A, it is easy to detect only the hit of the fish.
尚、第１図の実施例に於て、内層補強層９を小口５側ま
で延長しても良い。In the embodiment shown in FIG. 1, the inner reinforcing layer 9 may be extended to the small edge 5 side.
又、ＰＥＩ（ポリエーテルイミド）繊維は、透明性を有
するので、例えば外層補強層３を形成する時に、銘板等

In the case of a woven fabric or a non-woven fabric, the resin of the base material may be insufficient, so that the resin may be impregnated at that time.
第３図は第１図に示す釣竿Ａに釣糸ガイド１７を取り付
けた例を示す。FIG. 3 shows an example in which a fishing line guide 17 is attached to the fishing rod A shown in FIG.
釣竿本体１の所定箇所に釣糸ガイド１７を配し、その脚

と一体になっている。The fishing line guide 17 is arranged at a predetermined position of the fishing rod body 1, and the leg portions 18 are wound with a thread or tape made of PEI (polyetherimide) fiber to form the guide fixing portions 19, 19. The guide fixing portion 19 is cured to make the fishing rod main body 1
It is integrated with.
このガイド固定部１９によれば、濡れ性が良く、且つ、

り、釣糸ガイド１７が外れる虞もない。According to this guide fixing portion 19, the wettability is good, and
Since it is made of PEI (polyetherimide) fiber that has toughness and elongation, the adhesion and fixing strength are significantly improved compared to the conventional method, and when a load is applied, it is absorbed at this part and the fishing rod A is absorbed. There is no need to apply unnecessary force, and there is no risk of the fishing line guide 17 coming off.

ることが出来る。When the present invention is applied to the grip portion of the fishing rod,
The layer constituting the fishing rod main body is exposed at a specific portion such as a finger contact portion. According to this, the microvibration can be easily sensed, and the transmission of the microvibration can be mitigated because the other part is formed of the PEI (polyetherimide) fiber.

In this case, in addition to the above effects, PEI
Since the (polyetherimide) fiber has a lower specific gravity than carbon fiber or the like, the weight can be reduced.

所に設けても良い。Further, the present invention has been described for the case where the PEI (polyetherimide) fiber is provided in the outer layer, the inner layer and both ends of the elongated body formed of the reinforcing fiber impregnated with the synthetic resin, but it is necessary to improve the strength. PEI (polyetherimide) fibers can be appropriately provided at a certain portion. For example, it may be provided at the outer layer, the inner layer of the elongated body, or at one or a plurality of locations near both ends.

の利点を有する。As described above, according to the present invention, a long layer formed of reinforcing fibers impregnated with a synthetic resin is provided with a reinforcing layer made of polyetherimide fiber. Demonstrated by the reinforcing fiber impregnated with resin,
Impact resistance, tone, and feeling of use are exhibited by the reinforcing layer made of polyetherimide fiber. As a result, when the long body receives a shock such as a shock or a stone hit, the polyetherimide fiber absorbs and absorbs this shock, preventing the synthetic resin that constitutes the long body from being broken, and breaking or breaking. It has advantages such as prevention and scratch resistance, and mitigation of shock vibration.
