| 摘要 | A golf ball includes a spherical body and intersection surfaces. The intersection surfaces intersect with a spherical surface centered on the center of the spherical body, and are formed as conductive intersection surfaces having conductivity. The spherical surface is formed to have a smaller diameter than a diameter of the spherical body, and the conductive intersection surface is formed on an outer side in the radial direction of the spherical surface. The intersection surfaces intersect with a spherical surface centered on the center of the spherical body, and are formed as conductive intersection surfaces having conductivity. The conductive intersection surface is formed by both side surfaces of the annular body, and so the conductive intersection surface is formed to be continuous around the entire circumferential length of the spherical surface in the circumferential direction. | ||

| 主权项 | 1. A ball for a ball game comprising: a spherical body; and an intersection surface that intersects with a spherical surface centered on a center of the spherical body, and is positioned inward of an outer surface of the spherical body, the intersection surface being formed as a conductive intersection surface having conductivity, a height of the conductive intersection surface along a radial direction of the spherical body being at least 200 μm. | ||
