## Abstract

An electrical connection component includes a connecting part that is electrically conductive, and an electrical contact on at least a part of a surface of the connecting part, the electrical contact including a graphene oxide film. The graphene oxide film is graphene oxide or a stack of graphene oxide, and a thickness of the graphene oxide film is 1 nm or more and 50 nm or less. The electrical connection component may be either a male terminal or a female terminal.
