Abstract

A detection probe for detecting the electrical characteristics of a test piece is disclosed. The detection probe may include: a lead unit; and a terminal unit connected to the lead unit in a longitudinal direction. One of the lead unit and the terminal unit may include an engagement extension extending in the longitudinal direction and including a locking portion recessed in the radial direction. The other of the lead unit and the terminal unit may include an engagement receiving portion comprising: an edge portion formed by a plurality of slits extending in the longitudinal direction to be elastically changeable in the radial direction; and an engagement portion formed in the edge portion and engaging with the locking portion to prevent separation of the engagement extension in the longitudinal direction, and the engagement receiving portion receiving the engagement extension in the longitudinal direction.
