Patent attributes
An object of the present invention is to make it possible that a probe for testing electrical characteristics of an object to be tested is easily attached to a support member such as a contactor. A through hole is formed in the contactor. In the probe, a fitting/locking portion which can be fitted in this through hole is formed. The fitting/locking portion is formed to penetrate the through hole of the contactor and to be locked in the contactor in a state that a tip thereof is in contact with a connecting terminal of a printed wiring board. The fitting/locking portion itself is locked in the contactor by hooking a locking portion thereof to an end face on an upper side of the through hole.
