った。For example, a guide member made of steatite is
Since the hardness was low and the wear was remarkable, yarn breakage was apt to occur. The guide member made of alumina ceramics
Because of its low mechanical strength, it is easily broken, and it has been difficult to obtain a glossy surface for giving a sense of quality.

切れを生じやすいなどの問題があった。Further, the guide member made of zirconia ceramics has a low hardness, and silica (SiO,
Since it is equivalent to SiO 2 ) and the like, wear and tear were likely to occur when used in the sea or river. Furthermore, since the sliding characteristics are poor (the coefficient of friction with the line is high), there has been a problem that the fishing line is damaged and the line breaks easily.

できる。That is, the ceramics constituting the fishing line guide member of the present invention contains alumina as a main component,
It is possible to maintain the characteristics of high corrosion resistance and high wear resistance inherent to alumina, and to strengthen the bonding force between particles by adding a small amount of silica and / or magnesia to cause a solid phase reaction. In addition, by containing zirconia and / or zircon, the crystal grain size is adjusted by these phase transformations and the compressive effect due to partial particle expansion between the particles improves the wear resistance and strength of the ceramics and provides gloss. A surface is obtained, and the decorativeness can be improved.

Further, the content of these components is set to 0.1.
The reason for setting the content to 3 to 5.0% by weight is that if the content is less than 0.3% by weight, the sinterability is reduced. This is because grain boundaries are peeled off and cause significant wear.

０重量％を超えると硬度が低下するためである。[0015] Zirconia and zircon increase the wear resistance and strength of the sintered body by a compression effect due to volume expansion accompanying the phase transformation of the crystal, and constitute small crystal particles having a small particle size as described later. It has the effect of reducing the coefficient of friction on the fishing line. Further, by containing these components, the surface of the sintered body can be made glossy and the decorativeness can be enhanced. The content of these components is 3.0 to 45.
The reason why the content is set to 0% by weight is that if the content is less than 3.0% by weight, not only the sinterability is reduced but also the gloss cannot be obtained.
If the content exceeds 0% by weight, the hardness decreases.

Constitutes relatively large coarse crystal grains of 3 to 10 μm, and when both are mixed, the surface thereof has an appropriate uneven shape, whereby the friction coefficient to the fishing line can be reduced and the damage to the fishing line can be reduced.
【００１８】また、全体の平均結晶粒子径を７μｍ以下
としたのは、７μｍを超えると釣糸に対する摩擦係数が
高くなるためである。The reason why the overall average crystal grain size is 7 μm or less is that if the average crystal grain size exceeds 7 μm, the coefficient of friction with the fishing line increases.

And coarse crystal particles mainly composed of Al 2 O 3 can be distinguished from the appearance of darkness, and the average diameter may be determined by the cutting method of JIS H0501.
