A first needle-like member includes a columnar member formed by a conductive material such as a metal material with its up-and-down direction being longitudinal, and a contact member formed on a semiconductor integrated circuit (body to be contacted) side with respect to the columnar member, which are integrally formed. In the columnar member, a through hole is formed in the longitudinal direction of the first needle-like member. The through hole has opening ends on both sides thereof Thus, in the process of manufacturing the needle-like member, the contact member is formed on a rod-like body being a raw material from the same direction as a drill insertion direction to form the through hole.
