<p><P>PROBLEM TO BE SOLVED: To secure reliability at higher levels in a wiring board with built-in parts and to provide its manufacturing method. <P>SOLUTION: The wiring board with built-in parts comprises: conductive embedded layers formed in a board thickness direction without revealing in the upper and lower sides of the board; electric/electronic parts with terminals embedded in the board so that the terminals might counter the embedded conductive layer; a connection material for connecting the terminals and conductive layers electrically and mechanically having an upper and lower directional size incorporated in an upper and lower directional dimension of the conductive layer, in the gap provided between the terminals of embedded electric/electronic parts and the conductive layers; and two upper and lower insulating layers provided so that they might cover the surface except the part connected to the connection material among the surfaces outside the embedded electric/electronic parts and might stick to the board thickness direction of the upper and lower sides of electric/electronic parts. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
