First conductors and first insulators are alternately arranged one by one in a first direction in a first region. The first insulators and second insulators are alternately arranged one by one in the first direction in a second region. The memory pillar penetrates the first conductors and the first insulators in the first region and includes a semiconductor. A second conductor includes first to third portions. The second portion electrically couples the first portion and the third portion. A side surface of the third portion is electrically coupled to the semiconductor. A first film extends along the first direction in the second region. A second film contacts the first film, extends along the first direction, and includes carbon or metal. One of the second insulators includes a portion extending along the first and second films in the second region and being distanced from the second film.
