PRINTED BOARD AND METHOD OF MANUFACTURING PRINTED BOARD

摘要

PROBLEM TO BE SOLVED: To provide a printed board capable of stably holding a thermally conductive member even under a vibration environment, and a method of manufacturing a printed board.SOLUTION: The printed board is used which includes: an insulating substrate provided with at least one through hole; a conductor pattern layer formed on both surfaces of the insulating substrate; a first metal plating layer covering an inner wall of the through hole and the conductor pattern layer formed on both surfaces of the insulating substrate; a metal thermally conductive member arranged in the through hole so as to be in close contact with the first metal plating layer; and a second metal plating layer formed on both surfaces of the insulating substrate so as to continuously cover the conductor pattern layer and an end surface of the thermally conductive member.
