Patent ID: 11602049

Abstract:
A circuit board includes a protective film of such a type that a mating contact slides on the protective film and rides over a pad, and is prevented from deteriorating due to attachment and detachment. A circuit board 10 includes a plate-shaped base body 40, a pad 20 formed on a surface of the base body 40 and responsible for electrical contact with a mating contact, and a protective film 30 that spreads on the surface of the base body 40 in contact with an edge of the pad 20. The edge of the pad 20 and a portion, which contacts the edge of the pad 20, of the protective film 30 respectively have heights consecutive to each other. The pad 20 contacts, by causing the mating contact that has slid in a sliding direction in contact with the protective film 30 to ride over the pad 20, the mating contact that has ridden over the pad 20.
