Moreover, the first wiring layer including the first connection part is covered with a second insulating layer. The second insulating layer is formed of a first resin film and a second resin film. The second resin film contains fewer inorganic fillers than the first resin film. Thus, there is an advantage that a through-hole can be easily formed. | 05-14-2009 |
