摘要： A thick-film conductor circuit wherein a zinc-containing layer containing 3 to 20 atm% of zinc atoms with respect to copper atoms is formed in a thickness of 0.1 to 5 mu m in an area 5 mu m deep from the surface of a conductor made of a copper, or a thick-film conductor circuit having a rectangular sectional shape in the direction of width of the conductor and having rounded corners (R) at both lower end edge portions. This circuit is formed by using an aluminum plate treated with a zinc-containing basic solution as a conductive substrate, applying a specific liquid photosensitive resin composition to the conductive substrate, exposing a portion, where a resin pattern is to be formed, to high energy rays, dissolving or dispersing and removing an unexposed portion of the photosensitive resin composition by a developing solution to form a desired resin pattern on the conductive substrate, forming a conductor by electrolytic plating by applying a voltage to the conductive substrate while it is immersed in a plating solution, and removing the conductive substrate.
