Abstract: A method of manufacturing a contact probe includes: forming external shapes of a plurality of main body part base materials on a plate material, each of the plurality of main body part base materials being connected to a base part via a connection part and used for forming a main body part of a pipe member; forming a plurality of protrusions on each of the plurality of main body part base materials; forming the pipe member by bending each of the plurality of main body part base materials into a C-shape such that the protrusions protrude toward an inner side of the pipe member; assembling the contact probe by inserting first and second plungers and a coil spring into the pipe member connected to the connection part; and cutting the pipe member from the connection part.
