Abstract: An indoor unit for an air-conditioning apparatus includes a main body attached to an attachment portion, a heat exchanger attached to the main body and configured to exchange heat between air and refrigerant, a fan attached to the main body and configured to send, into a room, air subjected to heat exchange in the heat exchanger, and a front frame attached to the main body by using a screw. The front frame forms a fan casing that accommodates the fan between the front frame and the main body and through which air sent by the fan passes. The fan casing has an air outlet through which air is blown out, between a front air passage wall on a front side of the fan casing and a back air passage wall on a back side of the fan casing. The back air passage wall has, at a downstream terminal end, a recess into which the screw is inserted. The indoor unit further includes a screw cover covering the screw and attached to the recess.
