Abstract:
A flexible multilayer wiring board, comprising:first and second flexible base materials, each having a bonded surface bonded with an adhesive and an unbonded surface; and a first conductive body that electrically connects a first conductive pattern formed on the unbonded surface of the first flexible base material and a second conductive pattern formed on the second flexible base material, wherein: the first flexible base material is provided with a first through hole and the first conductive body is provided in the first through hole; space is provided between the bonded surface of the first flexible base material and the bonded surface of the second flexible base material in the periphery of the first through hole; a conductive paste forming the first conductive body is filled in the space through the first through hole; an air path via which air in the space can escape is provide between the first and second flexible base materials, wherein no adhesive is formed in said air path.
