A valve device with a built-in orifice is manufacturable with low-cost. The valve body defines an accommodation recess which opens at the surface of the valve body and contains a valve element therein, a primary flow path and a secondary flow path connected to the accommodation recess, the valve element having a sealing portion for blocking direct communication between the primary flow path and the secondary flow path through the accommodation recess, and a through flow passage for making the primary flow path and the secondary flow path communicate through the valve element, wherein an orifice is formed in the through flow passage.
