Abstract
A push switch includes a substrate including a first electrode and a second electrode that are arranged on an upper surface of the substrate; a resilient member arranged on the first electrode over the second electrode of the substrate; and a light-transmitting member including a crosslinked product of a chain olefin-cyclic olefin copolymer. The light-transmitting member covers the resilient member from above and includes an upper surface, a lower surface, a peripheral side surface between edges of the upper surface and edges of the lower surface of the light-transmitting member, and a periphery of the lower surface of the light-transmitting member. The periphery may be fixed on the substrate.
