The semiconductor layer comprises: a first portion extending in the first direction and facing a plurality of the control gate electrodes; and a second portion provided on a closer side to the substrate than this first portion. A film thickness of the first portion in the second direction is larger than a film thickness of the second portion in the second direction.
