A substrate processing apparatus of a simplified structure, which is capable of decreasing an amount of a process liquid to be used, and of restraining change in temperature of the process liquid is provided. The substrate processing apparatus includes: a processing unit that holds one substrate and processes the substrate held by the processing unit; a processing bath capable of simultaneously accommodating a plurality of substrates, the processing bath storing a process liquid into which a substrate is immersed so as to be processed, the process liquid being circulatingly supplied to the processing bath; and a transfer unit that simultaneously transfers substrates whose number is less than the number of substrate that can be accommodated in the processing bath. The transfer unit transfers, at least, to the processing bath in which the process liquid is stored. A substrate is processed with the use of at least one of the processing unit and the processing bath. |
