To solve a problem that an outlet bar forming a conventional power source line is made by insert molding through extrusion molding, using a high-cost exclusive devices.

The outlet bar 1 is provided with a base material for attaching 2 equipped with a base-material rear face 2a and base-material both side faces 2b, locking sides 2c with tip sides of the base-material both side faces 2b bent in acute angles, a rear face for mounting 3a of a mounting member 3 to be bonded to the base-material rear face 2a, both side faces for mounting 3b extended from the rear face for mounting 3a, a concave groove for locking 3c extended from each side face for mounting 3b, a concave groove for flange-part insertion 3d extended from the concave groove for locking 3c, an electrode plate insertion part 3e opened at an inside of the rear face for mounting 3a and the concave groove for locking 3c, and an electrode plate 4 to be inserted into the electrode plate insertion part 3e. The electrode plate 4 is inserted from an end part in a length direction of the electrode plate insertion part 3e of the mounting member 3, and the mounting member 3 is inserted from an end part in a length direction of the base material for mounting 2 to complete the assembly.
