1. A heat-exchanger fixing plate to fix a side portion of a heat exchanger to a housing panel of an air-conditioning apparatus, the heat exchanger including a heat radiation fin and a heat transfer tube, the heat-exchanger fixing plate comprising:
a heat-exchanger support portion facing the side portion of the heat exchanger, and having an insertion hole through which a hairpin portion of the heat transfer tube of the heat exchanger is inserted; and
a housing-panel fixing portion formed separately from the heat-exchanger support portion, fitted to the heat-exchanger support portion, and detachably engaged with the heat-exchanger support portion, the housing-panel fixing portion being fastened with a screw to the housing panel such that the heat exchanger is fixed to the housing panel,
the housing-panel fixing portion being made of material having a higher mechanical strength than a mechanical strength of material of which the heat-exchanger support portion is made,
the heat-exchanger support portion being made of the material having a lower friction coefficient than a friction coefficient of the material of which the housing-panel fixing portion is made.
