A connector (10) includes a set of type 1 contacts (4A) disposed in a type 1 holding area, the type 1 contacts (4A) being disposed facing each other, and a type 2 contact (4B) disposed in each of two type 2 holding areas sandwiching the type 1 holding area. When viewed from above, at least a portion of the type 2 contact (4B) is disposed in a range obtained by extending, in a first direction in which the type 1 holding area and the two type 2 holding areas are arranged, a region in which the set of type 1 contacts (4A) oppose each other in a second direction orthogonal to the first direction. Additionally, the type 2 contact (4B) includes a connecting portion that is connected to the circuit of the circuit board, and a contacting portion that is disposed at a position separated, from the connecting portion in a normal direction of an installation surface to the circuit board, and that contacts a terminal of a mating connector.
