Abstract:
A printed wiring board, comprising:an upper plate-like wiring substrate having conductive layers formed upon top and bottom surfaces thereof, wherein said upper wiring substrate has a first plated through-hole formed therein which is filled with a non-conductive material; a lower wiring substrate attached on said bottom surface of said upper wiring substrate, wherein said lower and upper wiring substrates combine to form a body having a cavity to receive a first electronic part within an inside thereof; a first connector land to mount the first electronic part thereupon, being provided with one of the conductive layers formed on a bottom surface of said first plated through-hole, which is formed on said bottom surface of said upper wiring substrate within the cavity; and a first external electrode, formed with a second plated through-hole, to electrically conduct between one of the conductive layers on the top surface of the upper wiring substrate and a conducive layer formed on a bottom surface of said lower wiring substrate, wherein said first external electrode is formed on a side-end surface of the body of said printed wiring board formed by combining said upper wiring substrate and said lower wiring substrate.
