Abstract
A contact probe includes: a first and second plungers, one of the first and second plungers being connected to an object to be inspected, the other being connected to an inspecting board; and a spring urging the first and second plungers so as to be separated from each other. The first plunger includes a distal end side columnar part and a flange part. The flange part includes a first portion that has a first length from a center point, which is, greater than a radius of the distal end side columnar part, in a first direction perpendicular to an axial direction, and includes a second portion that has a second length from the center point, which is smaller than the radius of the distal end side columnar part, in a second direction perpendicular to the axial direction and different from the first direction.
