Provided is an accumulator (1) capable of effectively suppressing a bumping phenomenon and the following impact noise without making the structure of the accumulator complicated or increasing the cost and the size thereof. A protrusion serving as an origination of boiling is disposed at a part soaked with a liquid part including liquid-phase refrigerant and oil accumulated in the tank (10) of the accumulator (1). Especially the protrusion is disposed at least at a part of an outer periphery of the outer pipe (32) in a double-pipe structure, and an inner periphery and an upper face of a bottom of the tank (10). |
