A contact hole is formed in a protective film 9 so as to communicate with an upper electrode 15. In the contact hole is formed a conductor 13 made of substantially the same material as used for the upper electrode 15, so as to communicate with the upper electrode 15 and extend to the outside of the contact hole. The conductor 13 is electrically connected to a memory cell transistor, by a wiring layer 14.
