A temperature adjustment device includes a pedestal to receive a substrate thereon, a first temperature control unit to set a first medium at a first temperature, and a second temperature control unit to set a second medium at a second temperature that is higher than the first temperature. A pedestal flow passage is provided inside the pedestal to allow the first medium and the second medium to flow therethrough by switching between the first medium and the second medium. A first flow passage through which the first medium flowing from the pedestal flow passage is allowed to flow is provided. A second flow passage through which the second medium flowing from the pedestal flow passage is allowed to flow is provided. A heat pump is connected to the first flow passage and the second flow passage to transfer heat between the first medium and the second medium.
