Abstract:
A wiring circuit board includes two insulating layers, a wiring layer, a pad portion, and a conductive connection portion. The wiring layer is on one side in a thickness direction of the first insulating layer, and has a contact portion. The second insulating layer is on one side in the thickness direction of the first insulating layer to cover the wiring layer. The pad portion is on one side in the thickness direction of the second insulating layer. The second insulating layer has a through opening portion and having an opening along at least a part of a peripheral end portion of the pad portion. The contact portion of the wiring layer faces the through opening portion. The conductive connection portion, is connected to at least the peripheral end portion of the pad portion, and the contact portion, and electrically connects the wiring layer to the pad portion.
