PURPOSE:To light only the desired character clearly in an operation button having the internal lighting. CONSTITUTION:In an operation button provided with plural light sources 24a, 24b for internal lighting, projecting parts 19a, 19b of a transparent primary molding 22 are exposed over the surface of a shading secondary molding 23 to form characters, which correspond to the light sources 24a, 24b separately. A through hole 50 is formed so as to divide the projecting parts 19a, 19b of the primary molding 22, and a shading wall 26 projected from the through hole 50 is formed integrally with the secondary molding 23. Consequently, the light emitted toward each projecting part 19a or 19b is not leaked to the undesired projecting part 19b or 19a, and only the desired character can be lighted clearly.
