Abstract

In a known indoor unit, a casing may move away from a wall surface and a gap may be formed between the casing and the wall surface, with the result that the design of the indoor unit may be deteriorated. An indoor unit includes a mounting board fixed to a wall surface and a bottom frame (casing) attached to the mounting board. The bottom frame (casing) has screw holes (screw fixing portions) for fixing the bottom frame (casing) to the wall surface of the room.
