A scroll compressor is provided that is configured to increase the amount of refrigerant injected into a target compression chamber to which refrigerant is desired to be injected. The scroll compressor has a fixed scroll that has a first base plate with an injection-pipe connection port to which an injection pipe is connected, a first injection hole that passes through the first base plate and communicates with one of the compression chambers, a communication hole that communicates with the injection-pipe connection port and the first injection hole, a second injection hole that passes through the first base plate and communicates with one of the compression chambers with which the first injection hole communicates, and a groove that is formed in a face opposite to a face on which a first scroll wrap is formed and communicates with the first injection hole and the second injection hole.
