PROBLEM TO BE SOLVED: To provide a trigger type liquid sprayer which can be formed by an easy assembling operation, can further improve the sealability of a suction valve, can form a liquid passage from the suction valve to a discharge valve in an injection cylinder so as to narrow as much as possible, and makes a pressure of a pressurized region high. SOLUTION: A suction valve body 34 always energized to the upstream side is pressure-contacted with a suction valve seat 24 at the tip of a cylindrical body D fitted and fixed to a rear side of the injection cylinder 12 to form a suction valve 35, and a communicating passage 23 communicating with the inside of a cylinder and the pressurized region is formed between the cylindrical body D and the injection cylinder 12. As a result, the cylindrical body D corresponding to the length of the injection cylinder 12 can be adopted, thereby eliminating a useless space in the injection cylinder 12.
