WIRING BOARD AND METHOD OF MANUFACTURING THE SAME

摘要

PURPOSE: A wiring board and a manufacturing method thereof are provided to obtain superior high frequency characteristics of a wiring board by preventing the increase of conductor loss due to skin effect. CONSTITUTION: A flat core material(20) formed of epoxy resin containing glass fiber is arranged on a wiring board(10). A laminate in which an insulating layer and a conductor layer(40,41) are alternately laminated are arranged on both sides of the core material. A solid conductor pattern connected to a fixed potential such as a power supply voltage or ground potential is formed in each conductor layer.
