PURPOSE: To provide a sheet having a movable contact point and a structure of a sheet switch wherein countermeasures for cost saving are enabled by reducing number of parts and operation feeling is made to be superior when the movable contact point is pressed down, and invasion of dust is prevented and a high contact reliability is obtained. CONSTITUTION: This is equipped with a sheet 1 made by an insulating film having an adhesion surface on whose lower surface an adhesive 2 is coated, and a movable contact point 3 which has a dome-shaped swelling part and whose upper face is covered and pasted by the adhesion surface of the sheet 1, and at the sheet 1, a linear notch 1a is formed extending toward a direction of a top part 3a of the swelling part across an outer peripheral end part 3b of the movable contact point 3. (과제) 부품점수를 삭감함으로써 저가 대응을 가능하게 하고, 가동접점을 눌렀을 때의 조작느낌을 양호하게 함과 동시에 먼지나 티끌의 진입을 막아 높은 접촉신뢰성을 얻을 수 있는 가동접점부착 시트 및 시트 스위치의 구조를 제공한다. (해결수단) 하면에 접착제 (2) 가 도포된 접착면을 갖는 절연필름제 시트 (1), 및 돔형상 팽창돌출부를 가지며 시트 (1) 의 접착면에 상면이 덮여 접합된 가동접점 (3) 을 구비하고, 시트 (1) 에는 가동접점 (3) 의 외주단부 (3b) 를 가로질러 팽창돌출부의 정상부 (3a) 방향을 향하여 연장되는 직선형상의 틈 (1a) 을 형성했다.
