AIR CONDITIONER

An air-conditioning apparatus includes a housing having an opening port and an air passage formed in the housing and connected to the opening port; an air-sending device installed in the housing and configured to generate an air flow in the air passage; a heat exchanger disposed in the air passage and configured to cause air and a heat medium to exchange heat; a fan guard installed on the housing with a gap defined between the fan guard and a face of the housing in which the opening port is provided, the fan guard preventing a contact with the air-sending device; and a filter attached to the housing such that the filter is inserted into the gap, the filter covering the opening port. The fan guard is installed on the housing such that the gap is narrowed toward an inward portion in an insertion direction into which the filter is inserted.
