PROBLEM TO BE SOLVED: To provide an operation switch structure hardly causing damage such as a bruise in a part to which a pusher contacts, easily keeping a predetermined operation feeling over a long period, and easily manufacturable. SOLUTION: This operation switch structure includes, in a base body part 14 arranged separately from and oppositely to a pressing operation part 15, a flat part and an elastically-deformable dome part 17 projecting from the flat part at a position corresponding to the pressing operation part 15. The flat part and the dome part 17 are covered with a sheet member 19. The sheet member 19 includes, at a position corresponding to the center part of the dome part 17, the pusher 21 projecting toward the pressing operation part 15. The operation switch structure is structured such that the dome part 17 can be elastically deformed through the pusher 21 by pressing the pressing operation part 15. The sheet member 19 and the pusher 21 are formed integrally with each other by using elastomer. The sheet member 19 is tightly fitted to surfaces of the dome part 17 and the flat part and fixed by adhesiveness of the sheet member 19. COPYRIGHT: (C)2008,JPO&INPIT
