Semiconductor device and method of manufacturing the same

A semiconductor device, comprising:

• a stacked body including a plurality of first conductive films stacked via an inter-layer insulating film;
• a first conductive body contacting the stacked body to extend in a stacking direction;
• a plurality of first insulating films in the same layers as the first conductive films and disposed between the first conductive body and the first conductive films,
• the first conductive body including a projecting part that projects along tops of one of the first insulating films and one of the first conductive films, and a lower surface of the projecting part contacting an upper surface of the one of the first conductive films;
• and
• a second insulating film configured from a material different from that of the first insulating film, disposed on the one of the first conductive films of the stacked body, and disposed in the same layer as the projecting part of the first conductive body.
