Abstract: A circuit pattern is obtained, capable of being easily applicable to current increase, making short circuit or ion migration between adjacent circuit conductors hard to be generated, and allowing a circuit pattern to be tightly arranged. A circuit pattern comprises a circuit conductor to be layered on a metal substrate through an insulating layer, an intermediate portion in a layer direction having a swelled shape in a layer-crossing direction in a cross section of the circuit conductor, and the swelled shape is formed by a gentle face in the layer direction.
