Ball for Ball Game
First Claim
1. A ball for a ball game, comprising:
- a spherical body formed by winding yarn having radio wave transmissivity into a spherical shape; and
a reflecting portion having radio wave reflectability formed on a spherical surface whose center is the center of the spherical body, whereinat least a portion of the yarn is given radio wave reflectability, andthe reflecting portion is configured from the portion of the yarn that has been given radio wave reflectability.

Abstract
A hard baseball ball is configured including a core layer, an intermediate layer, and the cover layer. The intermediate layer is formed on a spherical body by winding yarn having radio wave transmissivity, which allows radio waves to pass through, in a spherical shape around the core layer. The cover layer covers the intermediate layer, and is formed from a material with radio wave transmissivity. The hard baseball ball also includes the reflecting portion. The reflecting portion is formed on a spherical surface whose center is the center of the spherical body, and has radio wave reflectability. The reflecting portion is configured using yarn from which the intermediate layer is formed. At least a portion of the yarn from which the intermediate layer is formed is given radio wave reflectability, and the reflecting portion is configured from the portion of the yarn that has been given radio wave reflectability.
