A movable contact assembly includes a base having a sheet shape having a first surface and a second surface opposite the first surface, an operation portion projecting from the first surface of the base, an elastic portion having a domical shape and a elasticity for connecting the second surface of the base to the operation portion, and a contact on the operation portion. The operation portion has a surface facing in a facing direction identical to a facing direction of the second surface of the base. The surface of the operation portion is positioned in a direction with reference to the second surface of the base, and the direction is directed from the second surface of the base towards the first surface of the base. The operation portion projects from the first surface of the base. The elastic portion connects the second surface of the base to the operation portion. The elastic portion is thinner than the base. A remote controller including the movable contact assembly is thin and is manipulated.
