Picks for stringed instruments, such as guitar picks,
Traditionally, acrylic resin, polycarbonate resin,
Synthetic resin such as vinyl chloride resin or nylon resin is molded into the shape shown in Figure 1, or
It was manufactured by punching out the above-mentioned synthetic resin plate of 1 mm or less.

提供できるものである。
This invention creates a composite board in which the weight ratio of carbon fiber and synthetic resin is set in the range of 0.25 to 2.5,
By punching this into the desired shape and making picks, we manufacture picks that are thinner than conventional ones, have improved elasticity, and have very little wear.
This is something that can be provided.
以下、この発明の一実施例を詳細に説明する。 Hereinafter, one embodiment of the present invention will be described in detail.

より、第１図に示す形状のピツク１を得た。Example 1 As shown in Figure 2, epoxy resin was applied to a thin fabric 2 with a thickness of 0.3 mm made of high-strength carbon fibers woven by warp and weft in a weight ratio of 1:1. Glass plate or metal plate impregnated and treated with a mold release agent (hereinafter referred to as mold release agent treated plate 3)
A plurality of sheets are stacked on top of each other, and a similar release agent-treated plate 3 is placed on top of this, and a slight pressure is applied to form a 130
It was cured and molded under heating conditions of 1 hour at 100°C, and punched to obtain a pick 1 having the shape shown in FIG.
実施例 ２
実施例１において、0.3mmの薄い織物２を複数
枚積層したが、この代わりに、厚い織物を用い、

後、打き抜きにより、第１図に示す形状のピツク
１を得た。Example 2 In Example 1, a plurality of 0.3 mm thin fabrics 2 were laminated, but instead of this, a thick fabric was used,
This was impregnated with an epoxy resin at the same weight ratio as in Example 1, heated and pressed in the same manner, and after curing was punched out to obtain a pick 1 having the shape shown in FIG.
実施例 ３
実施例１において、0.3mmの薄い織物２を複数
