Electric valve

An electric valve comprising:

• a motor including a rotor member, a stator member for applying a rotational force to the rotor member, and a can in which the rotor member is disposed;
• a power transmission mechanism for converting rotational movement of the rotor member into axial movement of a valve body;
• a housing for accommodating the motor and the power transmission mechanism;
• and
• a base member connected to the housing and provided with a valve seat to which the valve body is separated or seated,
• wherein:
• the housing includes:
• a heat generation portion formed of a first material,
• a heat receiving portion formed of a second material and bonded to the heat generation portion, and
• a tube-shaped member and a cover member for shielding the tube-shaped member,
• a laser light transmittance in the first material is lower than a laser light transmittance in the second material,
• the heat generation portion is a part of the tube-shaped member, the heat receiving portion is part of the cover member, the cover member holds a substrate provided with a drive circuit for driving the motor, and the tube-shaped member is provided with a connector portion that can be connected to an external power source,
• the cover member includes an insertion portion that fits inside an end portion of the tube-shaped member, and ribs formed on an outer peripheral surface of the insertion portion,
• the motor is disposed on the tube-shaped member, and an angle sensor for detecting a rotation angle of the rotor member is disposed on the cover member, and
• the can of the motor is disposed between the angle sensor and the rotor member.
