PROBLEM TO BE SOLVED: To provide an electro-conductive circuit member to form an electric wiring pattern riding over a plurality of flat surfaces of resin molds with a plating process and to overcome faults in the plated layer at the ridge areas of the plurality of adjacent flat surfaces, and to provide a method for manufacturing the same electro-conductive circuit member. SOLUTION: The electro-conductive circuit member may be used in an ink cartridge, a cartridge holder 30, or a head cartridge in an image forming apparatus of the ink-jet system. This electro-conductive circuit member is provided with a first surface 18a, a second surface 18b crossing the first surface 18a, and a third surface 26 connecting these first surface 18a and the second surface 18b. Moreover, the circuit member is also provided with an electro-conductive layer 25 formed by non-electrolytic plating bridging over the first and second surfaces 18a, 18b via the third surface 26. Width of the conductive layer 25 formed to the third surface 26 is wider than that of the conductive layer 25 formed to the first and second surfaces 18a, 18b and the third surface 26 is formed on the basis of surface symmetry for the symmetrical surface of the first and second surfaces 18a, 18b.
