A scroll compressor wherein an eccentric rolling bearing and a main rolling bearing have enhanced reliability achieved by controlling both the amount of supply of oil from a high-pressure region to a back pressure chamber and the amount of supply of oil from the high-pressure region to the eccentric rolling bearing and to the main rolling bearing. A scroll compressor provided with a back pressure chamber oil supply route (25) for supplying a lubricating oil (7) from a high-pressure region (21) to a back pressure chamber (22), and also with a compression chamber oil supply route (26) for supplying the lubricating oil (7) from the back pressure chamber (22) to a compression chamber (23), wherein one opening (25c) of the back pressure chamber oil supply route (25) passes through the seal member (24) in a reciprocating manner.
