Claims

[Scope of utility model registration request]

A first fiber-reinforced resin in which multiple grooves are formed in a direction intersecting the axis on the outer periphery of the ball-hitting part of the bat body made of aluminum, and resin-impregnated carbon fibers are wound around the outer circumference of the ball-hitting part, and a portion of the resin is embedded in the grooves. As the layers are formed,
Furthermore, a second fiber-reinforced resin layer is formed by wrapping resin-impregnated carbon fibers around the outer periphery of the carbon fibers in a direction crossing the winding direction, thereby forming a second fiber-reinforced resin layer. .
