A test terminal is provided to prevent a plug connected to a test equipment from being erroneously connected to a socket connected to a machine equipment and to prevent accident caused as a plug of a test equipment is erroneously connected. A socket(10) includes a plurality of plug coupling parts(12,14,16,18) electrically connected with each operation part of a machine equipment. A plug(20) includes a plurality of plug pins(22,24,26,28) connected with the plug coupling parts of the socket. The color of the plug coupling parts of the socket is different from that of the plug pins of the plug, whereby polarities of the plug pins of the plug are discriminated and connected with the plug coupling parts of the socket. The plug coupling parts of the socket include connection casings(12a,14a,16a,18a) each having a conductive connection piece(11a) conductively connected with the plug pins of the plug, and have each different color. Polarities of the plug pins of the plug are discriminated and connected with the connection casings of the socket.
