An electrical connecting apparatus includes a contact unit provided on a substrate to contact an electrode terminal of a test subject in response to receipt of a load. The contact unit includes multiple plate-like members stacked in the thickness directions of the plate-like members and supported on the substrate in such a manner that a contact surface formed at an end surface of each of the plate-like members contacts a wiring pattern on the substrate. At least some of the multiple plate-like members are contacts including a base, and an arm having one end supported by the base and an opposite end where a tip portion to contact the electrode terminal is formed. The arm has a surface to contact a surface of an adjacent one of the plate-like members to form a conductive path connecting the tip portion and the wiring pattern through the adjacent plate-like member.
