摘要： There is provided a baseball bat that has performance similar to that of the conventional wooden bat and moreover is excellent in terms of cost and resource conservation. For this baseball bat 11, a reinforcing core 12 having a rectangular cross section is arranged in the center of the cross section thereof continuously so as to penetrate both end thereof, bamboo pieces 24 are laminated around the reinforcing core 12, and an adhesive is caused to permeate into the contact surface between the reinforcing core 12 and the bamboo pieces 24 evenly under a pressure, by which firm bonding can be attained. In addition, by using a material that is hard and has a large specific gravity as compared with bamboo, such as hickory or reinforced wood, as the reinforcing core 12, the flexural rigidity is enhanced as a whole, and the weight is increased. Therefore, the characteristics and feel in use are improved as compared with the conventional bamboo bat, and the baseball bat 11 can be used as a substitute for a wooden bat. Bamboo, hickory, and reinforced wood have no problem in terms of resource conservation, can reduce the product price, and can lower the consumption of scarce resources such as serrata.
