Provided is a push switch, which provides good operation touch even if a movable region of a cover plate between a wall of a housing and a press member is the composition which becomes short in a predetermined direction. The push switch includes: a movable contact member (5) which deforms in response to pressing force to be contacted with contacts; a housing (3) of a receiving portion (4), the housing being provided with walls (3b) around, receiving the movable contact member inside and having contacts on an inner bottom surface (3a), wherein the distance among the walls is the shortest distance in a first direction; a cover plate (9) which enables end portions to be fixed to the walls in a way of covering the movable contact member in the receiving portion; and a press member (7) which transmits pressing force to a convex portion (5b) of the movable contact member in a state of being contacted with the cover plate, wherein a contact region where the press member contacts the cover plate in the first direction during deformation of the movable contact member in response to the pressing force is narrower than in other directions intersecting with the first direction.
