Abstract
In a solenoid valve, multiple flow-blocking portions are formed in a passage between a supply port (23) and an output port (24) and a passage between the output port (24) and a drain port (25). The flow-blocking portions, having an overlap length that corresponds to the movement amount of a spool (30), are formed by the outer peripheral faces of lands (32, 33) and the inner peripheral face of a spool case (10).
