    摘要: It is possible to obtain a clean high-quality circuit board by removing affected material and foreign matter produced when a hole is formed. A manufacturing method of the circuit board includes (a) preparing a film-coated board material (51) by bonding a film material (4a,4b) as a mask to a board material (1), (b) forming a hole (10) in the film-coated board material (51) by applying a laser beam (9) thereto, and (c) selectively removing the unnecessary material (11,12) sticking to the film-coated board material (51) from the film-coated board material (51) by supersonic cleaning without peeling the film material (4a,4b) off the board material. After removal of such unnecessary material, a conductive material (14) is disposed in the hole (10), using the film material (4a,4b) as a mask, and the film material (4a,4b) is later removed from the board material (1).
