Abstract: [Object] To provide a trigger sprayer including a valve through which liquid flows with very high efficiency.[Solution] The present invention is directed to a trigger sprayer for, in a state of being attached to a container, causing liquid inside the container to be sprayed from a nozzle part 3 through a passage by rotating a trigger part to move a piston part 5 to apply pressure to liquid inside a cylinder portion 42A of a cylinder structure 4, including: an F valve 2 provided in a passage between the cylinder portion 42A and the container; and an S valve 1 provided in a passage section between the cylinder portion 42A and the nozzle part 3, wherein the S valve 1 includes a first valve body 11 and a first valve seat 12, the first valve body 11 is oppressed against the first valve seat 12, and when the first valve body 11 moves away from the first valve seat 12 so that the S valve 1 opens, the first valve body 11 moves in the same direction as the direction that the liquid flows.
