Ball for ball game and method of manufacturing the same
First Claim
1. A ball for a ball game, the ball comprising:
- the ball is a spherical body,a spherical core inside the spherical body, the spherical core being a sphere having a center of the spherical body as a center,a spherical cover layer covering the spherical core, the spherical cover layer being a sphere having a center of the spherical body as a center,first and second regions formed on;
a spherical surface of the spherical core;
oran inner spherical surface of the spherical cover layer;
the first regions are formed of a first material, the first material being an electrically conductive material and having a radio wave reflectance, the first regions each having a diameter of not less than 2 mm and not more than 15 mm and the first material being a coating material, andthe second regions are formed of a second material in areas other than where the first regions are formed, the second material being an electrically non-conductive material and having a radio wave reflectance lower than the radio wave reflectance of the first material.

Abstract
A golf ball including a spherical body, first regions, and second regions. The spherical body includes a core layer and a cover layer made from a synthetic resin covering the core layer. Dimples are formed in a surface of the cover layer. First regions that are electrically conductive are formed on a surface of the spherical body. The first regions are formed on a spherical surface having a center of the spherical body as a center. The first regions are positioned at six vertices of an imaginary regular hexahedron such that the vertices are positioned on the surface of the spherical body and, thus, six of the first regions are formed. The second regions are formed in areas of the surface other than where the first regions are formed. The second regions have a radio wave reflectance lower than that of the first regions.
