Abstract
It is possible to make the free length of a contactor uniform even when the contactor is joined to a position that deviates from a joint position in a high-frequency conducting path and make contact with an electrode with stability, which improves measurement quality. A probe unit according to the present disclosure includes: a coaxial connector that is attached to a main body and gives and receives an electrical signal to and from a tester via a coaxial cable; a high-frequency conducting path that is connected to the coaxial connector and transmits an electrical signal; a plurality of contactors, each having a tip portion that makes electrical contact with an electrode of an object to be inspected and giving and receiving an electrical signal to and from the high-frequency conducting path; and a pedestal that is interposed between the contactor and the high-frequency conducting path, and the pedestal is provided in each contactor such that a free length of the contactor is a predetermined length.
