A contact terminal for measurement is provided, for transmitting a signal between a desired probe pin among a plurality of probe pins arranged in parallel at a predetermined distance in a predetermined direction on the surface of a probe substrate and an external measurement apparatus. The contact terminal for measurement includes: a signal terminal having an width smaller than the distance between the probe pins provided on both sides of one probe pin in the arrangement direction; two ground terminals to which a ground potential is applied, which are provided on both sides of the signal terminal in the arrangement direction and which have each width larger than that of the signal terminal in the arrangement direction; and a signal line electrically connecting the signal terminal to a signal input terminal of the external measurement apparatus.
