    摘要： A spool valve (1) includes: a sleeve (10) extending in an axial direction thereof, including an inlet port (11) and an outlet port (12) for working fluid; a spool (20) housed in the sleeve (10) in the axial direction; a biasing device (30) configured to press a base end (20a) of the spool (20) toward a tip end (20b) of the spool (20); and a pressure detecting port (56) opening toward the tip end (20b). The spool (20) includes: a first land section (21) located between the pressure detecting port (56) and the inlet port (11); a second land section (22); a groove section (23) located between the first land section (21) and the second land section (22), having a width in the axial direction capable of connecting between the inlet port and outlet port; a recess portion (27) formed on an outer peripheral surface of the second land section (22) ; and a connection passage (28) for the working fluid formed in the second land section, connecting between the groove section (23) and the recess portion (27). A path hole (50) is formed in the sleeve facing the recess portion of the spool.
