A pressing switch mechanism includes a housing, a board that is accommodated in the housing, a switch portion that is fixed to the board and generates a click feeling according to pressing a pressed portion in a direction approaching the board, and an operation plate which includes a bowl-shaped recessed surface that is recessed from a surface of the housing, of which an outer peripheral edge is supported by the housing, which is displaceably bent in the direction approaching the board, and in which a bottom wall portion of the recessed surface protruding inward the housing is in contact with the pressed portion.
