The multiple cylinder rotary compressor includes: a compressor body including a hermetic case, the hermetic case housing inside a rotating shaft, an electric motor section, and a compression mechanism body; the compression mechanism body including: at least three compression mechanism sections arranged so as to stack with each other in an axial direction of the rotating shaft, partition plates each of which disposed between the corresponding adjacent compression mechanism sections, and a primary bearing and a secondary bearing supporting the rotating shaft on both end sides of the compression mechanism body along the axial direction of the rotating shaft; and the compression mechanism sections each of which including: a cylinder forming inside a cylinder chamber, an eccentric section provided to the rotating shaft, disposed in the cylinder chamber, a roller fitted to the eccentric section, rotating eccentrically within the cylinder chamber, and a blade dividing the inside of the cylinder chamber into two. At least one partition plate of the partition plates constitutes a partition plate bearing supporting the rotating shaft.
