According to one embodiment, a rotary compressor accommodating an electric motor portion and a compression mechanism portion in a sealed case, wherein the compression mechanism portion comprises a cylinder, a roller, and a vane. The vane is disposed by stacking two divided vanes in a height direction of the cylinder, which is an axis direction of the rotation axis, and where a height dimension of one divided vane is H, and a minute gap between a height dimension of the cylinder and a height dimension of the two stacked divided vanes is L, a proportion of the minute gap L to the vane height dimension H per one divided vane is 0.001
