Abstract
An object is to obtain a scroll compressor that can reduce an outflow of injection refrigerant into an oil sump, reduce degradation of reliability associated with a decrease in viscosity of refrigerating machine oil stored in the oil sump, and reduce degradation of performance caused by compression of dead volume, and thereby achieve high efficiency, and to also obtain a refrigeration cycle apparatus. An injection port opens only to a suction chamber and is provided in a baseplate of a fixed scroll. In all phases of rotation of a rotation shaft, the injection port is located on an inner side of an outer edge of a structure unit that is configured by meshing a spiral body of the fixed scroll and a spiral body of an orbiting scroll with each other.
