PROBLEM TO BE SOLVED: To provide a connection circuit unit with a battery as a power source excellent in assembling property, enabled to keep sure contact with the battery by unitizing it with an electric circuit side by using a coil spring as one of the contact metal fittings for the battery. SOLUTION: The unit is constituted of a base plate 12 equipped with an electric circuit having a terminal at one pole side and a terminal at the other pole side, a fixing plate 22 positioning and fixing the base plate 12 at its one side face 23 so as to form a T-shape, a nearly cone-shaped coil spring 44 as a contact metal fitting 42 of the battery positioned and fixed to the other side face 26 of the fixing plate 22, and a plate-shaped contact metal fitting 52 of the other pole side of the battery, held through the fixing plate 22. The coil spring 44 is positioned so that its base end widened diameter part 45 opposes the other side face 26, and a open end part 47 led out from the base end widened diameter part 45 toward the one side face 23 of the fixing plate 22 is fixed to the terminal at one pole side in a positional relation nearly crossing a plate face of the base plate 12.
