Abstract

A power supply module configured to supply power to a load having a first connector terminal includes a body, an insulating member, and a second connector terminal. The body includes a frame for power supply. The insulating member seals the body such that the frame is exposed from the insulating member. The second connector terminal is configured to be fitted with the first connector terminal and is bonded to the frame.
