Abstract
A method of manufacturing an electric contact includes a welding step of welding a contact material (12) to a base material (11), and a crushing step of crushing the contact material (12), wherein one or more absorption holes (11a and 11b) that absorb deformation of the base material (11) in a thickness direction (Z direction) caused by the crushing of the contact material (12) are formed around the welding position of the contact material (12) on the base material (11).
