A plurality of conductor traces are formed on a porous base insulating layer made of porous ePTFE. Each conductor trace has a laminated structure of a seed layer and a conductor layer. A cover insulating layer is formed on the base insulating layer to cover each conductor trace. The ePTFE used as the porous base insulating layer has continuous pores. An average pore size of the ePTFE is not less than 0.05 μm and not more than 1.0 μm.
