Abstract
A membrane switch can attach an elastically deformable dome to a board in a reliable manner such that the dome is not detached even if a fixing sheet is made thinner and smaller and therefore has a smaller footprint. This switch has: a dome () that is formed projecting toward the surface and that is dented opposite toward the back surface by elastic deformation; and a flexible fixing sheet () that has a back surface of an adhesive face pasted to the entire face of the surface of the dome (). The fixing sheet () fixes the dome () in a predetermined position of a board () by means of a stretching part () which stretches radially outer to the dome (), from an outer rim () of the dome (), in a direction virtually orthogonal to a direction in which the dome () projects. A plurality of slits () formed in the fixing sheet () at predetermined intervals along the outer rim () of the dome (), prevent a stretching part () of the fixing sheet (), from joining with a dome covering part () which is a portion above the dome () that continues in the radial direction of the dome ().
