To provide an electrically-driven valve gear that is of a rational structure, including an electric drive part and its surrounding functional components.SOLUTION: In the electrically-driven valve gear, a drive device 32 that drives an expansion valve 13 has an electric drive part (motor) 42, a control circuit-equipped circuit board 45, and a temperature-pressure detection body 46 that detects the state of a coolant (temperature and pressure detection). The electric drive part, the circuit board and the temperature-pressure detection body are housed in a housing 40 and establish mutual electrical connection in the housing 40.SELECTED DRAWING: Figure 2
