A bus bar includes a body having at least one bent portion and a plate-shaped or bar-like terminal located on at least one end of the body and formed of a material identical with a material of the body integrally with the body in a seamless manner. The terminal is formed by pressurizing the end of the body thereby to be plate-shaped or bar-like and having a higher hardness than the bent portion. The body is solid and linear in shape. The terminal is formed so that its profile has a required predetermined size by adjusting an applied pressure value.
