Zusammenfassung:	Provided are a laser annealing apparatus, a laser annealing method, and a mask with which scan nonuniformity can be decreased. According to the present invention, all or some openings of a plurality of openings are configured so that a partial subregion of a prescribed region is irradiated with laser light. The plurality of openings are configured so that, between prescribed regions irradiated with laser light via a group of openings in one row arranged in a row direction and prescribed regions irradiated with laser light via a group of openings in another row arranged in the row direction, the number of times of laser light radiations in subregions having the same occupying region is the same, and at least two openings of a group of openings arranged in a column direction have different positions or shapes.
