An object of the present invention is to provide an electrical contactor highly resistant to deformation capable of achieving satisfactory performance of electrical contact with a small number of elements. An electrical contactor of this invention includes a barrel having a spring part achieving a spring function formed in a partial section, and a first plunger and a second plunger inserted in the barrel through an opening at one end and an opening at an opposite end of the barrel and fixed to the barrel. It is preferable that an end part of the first plunger in the barrel and an end part of the second plunger in the barrel are placed in internal space of the same non-spring part not to achieve a spring function. It is preferable that the barrel has three or more spring parts separated while non-spring parts are placed between the spring parts.
