SMOOTH PRINTED WIRING BOARD AND METHOD OF MANUFACTURING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a durable smooth printed wiring board which is suitable for such application that electrodes are slid. SOLUTION: The printed wiring board is constituted in such a way that a circuit board 5 having etched circuit pattern sections 3 and insulating recessed sections 4 and through holes 7 formed at places in the recessed sections 4 is thermocompression bonded to a prepreg 10, and the recessed sections 4 are filled up with a resin 11 via the through holes 7 until the surface of resin 11 is flush with the surfaces of the circuit pattern sections 3.
