1. A semiconductor device comprising:
a first circuit element chip including a first surface on which a plurality of first electrodes are arranged;
a second circuit element chip, including a first surface on which a plurality of second electrodes are arranged, which is mounted on the first circuit element chip, wherein the first surface of the first circuit element chip faces the first surface of the second circuit element chip;
an insulating film disposed on a side surface of the second circuit element chip, and disposed between the first surfaces of the first and second circuit element chips, wherein a gap between the first circuit element chip and the second circuit element chip is filled with the insulating film; and
a resin layer covering the first circuit element chip, the second circuit element chip and the insulating film.
