To provide a pump dispenser with a trigger, having a simple construction, the number of parts reduced, and remarkably excellent operability. In a pump dispenser ( 1 ) which jets liquid in a cylinder ( 4 g) from a nozzle portion ( 5 ) when a piston ( 7 ) integral with the nozzle portion ( 5 ) is pushed down according to grasping of a trigger ( 4 c), the cylinder ( 4 g) is integrally formed inside a barrel portion ( 4 a) disposed along an axial direction of a container and the trigger ( 4 c) is integrally formed on the barrel portion ( 4 a) via a hinge portion ( 4 b). Since the trigger is integrally formed on the cylindrical barrel portion disposed along the axial direction of the container via the hinge portion, a fulcrum for causing the trigger to pivot can be disposed as rearward as possible, so that a large leverage can be taken. Since at least the barrel portion and the trigger are integrally formed from synthetic resin, movement of the pivot fulcrum becomes remarkably accurate.
