Abstract:
1. A wired circuit board comprising: a first wired circuit board; and a second wired circuit board disposed to be opposed to the first wired circuit board in the same plane, wherein a first opposed surface of the first wired circuit board facing the second wired circuit board and a second opposed surface of the second wired circuit board facing the first wired circuit board comprise at least two types of interfitting surfaces extending in different directions so as to mutually interfit the first opposed surface with the second opposed surface, wherein the first wired circuit board comprises a first insulating layer and a first conductive layer laminated on a surface of the first insulating layer, such that the first conductive layer extends beyond a first opposed surface of the first insulating layer, the second wired circuit board comprises a second insulating layer and a second conductive layer laminated on a surface of the second insulating layer, such that the second conductive layer is set back from a second opposed surface of the second insulating layer, the interfitting surfaces are provided in longitudinal end portions along a thickness of the first conductive layer and the second conductive layer, a location of the interfitting surfaces of the first conductive layer and the second conductive layer is offset from a location of the first opposed surface of the first insulating layer and the second opposed surface of the second insulating layer when the first wired circuit board and the second wired circuit board are connected, such that the first and second opposed surfaces of the first and second insulating layers, respectively, contact each other, and the interfitting surfaces of the first conductive layer and the second conductive layer opposed to come into contact with each other define a first line of contact in a thickness direction, and the first opposed surface of the first insulating layer and the second opposed surface of the second insulating layer opposed to come into contact with each other define a second line of contact in the thickness direction, the first line of contact and the second line of contact being parallel to each other.
