To provide a vibration source fixing structure capable of reducing propagation of vibration occurring in a vibration source.

A compressor fixing structure for fixing a compressor 200 being a vibration source to a base plate 310 includes a compressor mounting leg 210 formed below the body of the compressor 200 and having a projection 211, a vibration absorption member 400 fixed on the base plate 310 and having a through-hole 401 in which the projection 211 is inserted, a sheet metal 410 fixed on the vibration absorption member 400 and having a through-hole 411 in which the projection 211 is inserted, and an insertion type fixture 500. The fixture 500 is mounted at a prescribed position by being attached from a prescribed direction so that the compressor mounting leg 210 is stored in a storage part 504 and the edge 412 of the sheet metal 410 is inserted in a groove 507, in a state of the projection 211 being inserted in the through-hole 411 and in the through-hole 401.
