A semiconductor device includes: a plurality of power MOS cells on a semiconductor substrate; a plurality of lead wires connecting to a source and a drain of each power MOS cell through a contact hole; a plurality of collecting electrodes connecting in parallel with the lead wires through a via hole; an interlayer protection film on the collecting electrode; a thick film electrode connecting to the collecting electrode through the opening; and a terminal protection film having an opening for bonding connection. The openings are formed in the interlayer protection film such that a portion between the openings becomes a beam shape
