Provided are contact member having a curved portion on which a plurality of projections are provided and a switch device using the contact member, which makes an operation feeling difficult to be deteriorated even if the position of a pressing point is outside from the center. On a contact member (10) which is formed of a metal leaf spring member, a curved portion (12) having a dome shape is formed, and around the center (O1), three projections (13a, 13b, 13c) are projected toward a substrate. The leaf spring member which forms the contact member (10) is extended in an X direction. The projections (13b, 13c) are disposed so that circular outlines thereof are not overlapped with a longitudinal center line (Ox), which extends in the extended direction. Therefore, it is possible to shift the position of the projections with respect to a direction in which the operation feeling is deteriorated by being affected by the extended direction of the member, and it is possible to expand an area where the operation feeling is not deteriorated extensively in the X direction and a Y direction when pressing a position apart from the center (O1). |
