1. A valve device comprising:
a valve block having a valve port through which a fluid passes and an insertion hole;
a valve body that opens or closes the valve port;
a guide member that is inserted in the insertion hole, and slidably guides the valve body;
a solenoid that generates a magnetic field when energized;
a stationary pole that cooperates with the solenoid to move the valve body;
a magnetic member that is arranged in the insertion hole and constitutes a magnetic circuit together with the solenoid;
a support member that is tubular and inserted in the insertion hole to accommodate the solenoid, and supports the guide member that receives pressure from the fluid passing through the valve port; and
a lid member that is joined to an inner circumferential face of the support member and closes an opening of the support member, wherein
the support member is joined with the valve block,
the magnetic member has a notch,
the valve block has an extraction hole connecting with the notch located in the insertion hole, on a lateral face,
the solenoid has a terminal projecting to the notch and facing the extraction hole, and
in the extraction hole, an energizing member that is connected with the terminal to energize the solenoid extends from a lateral side of the valve block.
