A contact terminal that enables a relatively large current to flow is provided. A contact terminal (10) includes a main body case (11), and a plunger pin (20) received in a non-penetrating elongate hole (13) formed in the main body case (11). The contact terminal (10) is provided for making electrical connection by contacting the protrusion end portion (21a) of the plunger pin (20) protruding from the main body case (11) with a target part. The plunger pin (20) is a round bar provided with a step, the round bar includes a small diameter portion (21) including the protrusion end portion (21a), and a large diameter portion (22) that slides on an inner surface of the non-penetrating hole to freely move in a longitudinal direction thereof, a cut space is formed to extend from an end of the large diameter portion (22) in the longitudinal direction thereof so as to leave at least a part of a side surface portion of the large diameter portion (22), and the cut space receives an insulation ball (30) including at least an insulation surface. A coil spring (31) is arranged between the non-penetrating hole (13) and the insulation ball (30) to press the protrusion end portion (21a) of the plunger pin such that the protrusion end portion protrudes from the main body case (11).
