PROBLEM TO BE SOLVED: To provide an electric selector valve capable of lowering the power consumption, restricting the generation of noise, restricting the manufacturing cost low, and hard to generate the leakage of a valve. SOLUTION: This electric selector valve is provided with a stepping motor 12 formed of a stator 13 and a rotor 17, a rotary valve element 20 to be integrally rotated with the rotor 12, and a valve seat member 20 arranged opposite to the rotary valve element 20. One flow-in port 31 and two flow-out ports 32, 33 are opened in a seat surface of the valve seat member 30, and one end surface of the rotary valve element 20 is provided with a closing projection part 21 for selectively closing the two flow-out ports 32, 33 in response to the rotation stop position while sliding with the seat surface, and the rotary valve element is provided with a key-like projecting part 24, and a valve holder 27 is formed with a key groove 28, in which the key-like projecting part 24 is loosely fitted. With this structure, even if a rotary axis of the rotor 17 is vibrated, this vibration is hardly transmitted to the rotary valve element 20.
