PROBLEM TO BE SOLVED: To provide a light emitting ball with high durability in which the impact resistance of a light emitting unit is improved. SOLUTION: The light emitting ball 20 is constituted by housing the light emitting unit 10 emitting light by impact or vibration in a hollow spherical body. The light emitting unit 10 is constituted of a light emitting element 1, a battery 2 for driving the light emitting element 1, a switch 5 operating by impact or vibration, a control circuit making the light emitting element 1 emit light by the operation of the switch 5, and a circuit board 9 for mounting the above parts, and is sealed in a spherical case 6. These parts are supported and secured with pushing ribs 12 to 15 protrudingly formed in the inner wall of the spherical case 6. COPYRIGHT: (C)2005,JPO&NCIPI
