ピン3の尖端部3aが突出した状態となる。Next, the upper mold 4 is lowered and the mold is clamped as shown in FIG. 1(B). As the mold is clamped, the pin 3 of the insert member 1 penetrates from the upper surface 7a to the lower surface 7b of the long fiber mat material 7, and its tip 3a protrudes from the lower surface 7b of the mat material 7. Next, as shown in Fig. 1(C), a thermosetting resin material is injected into the mold to fill the spaces between the long fiber materials, and a fiber-reinforced resin molding molded with a thickness of 2 mm is made. Form 8 flannel 9. The upper surface 2a of the disk portion 2 of the insert member 1 is exposed on the upper surface 9a of the molded panel 9, and the tip portions 3a of the eight pins 3 of the insert member 1 protrude from the lower surface 9b of the molded panel 9. The state will be as follows.

締めと同時に行なうことができる。As is clear from the above description, in this embodiment, the pins 3 of the insert member 1 penetrate the long fiber mat material 7 in which the long fiber material is movable prior to forming the panel 9. Therefore, there is no fear that the long fiber material will be cut by the pins 3, and the insert member 1 is not inserted into the upper mold 4.
By clamping the insert member 1 while holding it on the lower surface 4a of the mat member 7, the insert member 1 can be attached to the mat member 7 at the same time as clamping the insert member 1.
