To reduce noises when coolant passes through a motor-operated valve.
This motor-operated valve comprises a valve body 900 for adjusting coolant passing flow by a valve element 200, and a can 400 containing a rotor 300 for operating the valve element. A first communication hole 910 and a second communication hole 920 are drilled in the valve body. The valve element is provided to this motor-operated valve and can rotate and move between a position where any of the first communication hole and second communication hole is selectively closed and a position where either of the first communication hole and second communication hole is not closed. Two orifice formed parts whereinto orifices 224 are drilled are formed on the valve element. Porous members 226, 223 are arranged on the respective orifice formed parts such that the coolant having passed through the respective porous members joins at the flowout side.
