<p><P>PROBLEM TO BE SOLVED: To provide a wiring board which meets a requirement for enhancing electric reliability. <P>SOLUTION: The wiring board includes a plurality of inorganic insulating layers 5, a plurality of resin layers 6 interposed between the inorganic insulating layers 5, and a plurality of conductive layers 7 separated in a thickness direction through the inorganic insulating layers 5 and the resin layers 6. The plurality of resin layers 6 have a first resin layer 6a located on an uppermost layer of the resin layers 6, and the first resin layer 6a is smaller in a thickness than the other resin layers 6. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
