PRINTED WIRING BOARD, POLYOLEFINIC RESIN COMPOSITION, AND METHOD FOR MANUFACTURING OF PRINTED WIRING BOARD

摘要

PROBLEM TO BE SOLVED: To provide a printed wiring board having layer insulation resin layers using a polyolefinic resin composition easy to form openings of desired shapes even when a laser beam is used. SOLUTION: The printed wiring board has conductor circuits and layer insulation resin layers stacked one above the other on a board, the conductor circuits being connected by vias, and the layer insulation resin layers are made of a polyolefinic resin composition containing organic fillers and a polyolefinic resin.
