A checker head including an intermediate plate which is sandwiched between a front plate and a rear plate. A front tip part of an electro-conductive contact protrudes from a front surface of the front plate and is configured to contact an object to be inspected. A conductive wire is inserted into a rear through hole of the rear plate and bonded to the rear plate. An electro-conductive spring is provided in an intermediate through hole of the intermediate plate between the conductive wire and a rear brim part of the contact pin in a compressed state. One end of the conductive wire which contacts the spring and a front surface of the rear plate which faces the an intermediate plate is on a same plane.
