1. A solenoid valve, comprising:
a valve body;
a sleeve in which the valve body is accommodated;
a solenoid casing which is connected to the sleeve on a first end side in an axial direction of the solenoid valve, and which is closed on a second end side opposed to the first end side in the axial direction;
a solenoid molded body formed by molding a coil with resin and accommodated in the solenoid casing, the solenoid molded body including a connector portion having terminals electrically connected to the coil;
a yoke including a tubular portion disposed inside the solenoid molded body, and a flange portion projecting radially outward from an end portion of the tubular portion on the second end side; and
a movable iron core disposed to be movable in the axial direction inside the yoke,
wherein the valve body is moved together with the movable iron core by energizing a coil of the solenoid molded body,
the flange portion has an annular outer peripheral surface that is continuous, and is disposed between the solenoid molded body and the second end side of the solenoid casing
the solenoid molded body includes an abutting portion which abuts an end surface of the flange portion on a coil side, and
the connector portion of the solenoid molded body is formed by extending part of the solenoid casing continuously from the abutting portion in an outward radial direction so as to protrude outside the solenoid casing.
