An electrical connecting method has the step of bringing a contact member connected to an electric circuit into contact with a terminal of an electronic part. A desired processing is performed by feeding current to the terminal via the contact member. The contact member is then separated from the terminal. When the contact member is brought into contact with the terminal, energy is applied to the contact member or the terminal in order to locally soften a portion of the terminal contacting the contact member. Thereafter, the desired processing is performed, in the state that the contacting portion of the terminal with the contact member is softened so as to reduce the contact resistance and so as to increase the subsequent separatability of the contact member from the terminal.
