A coaxial terminal includes a signal terminal, a tubular ground terminal that covers the signal terminal, and an insulating member interposed between the signal terminal and the ground terminal. The signal terminal includes a main body that is covered by the insulating member, an upper contact piece that extends from the main body to +Z direction side, and a lower contact piece that extends from the main body to −Z direction side. The insulating member has an opening through which a part of the main body is exposed. A following formula (1) is satisfied:

L.sub.2≥½×L.sub.1  (1)

where L.sub.1 is a length of the insulating member along an axial direction of the coaxial terminal, L.sub.2 is a length of the opening along the axial direction.
