PURPOSE: A sprinkler head is provided to prevent a malfunction of sprinkling into only one direction by perforating a number of holes in a sheet plate to detect heat more rapidly. CONSTITUTION: A deflector(5) is integrally coupled with a joining section(41) in the lower part of a frame(4) integrally formed with an exit(42). A lever member defines a spring lever(31) and a central support(32) supported at the upper part of the joining section(41). The lever member has a cap supported at the upper part of the central support(32) to enclose a supply piping and a pair of sheet plates(21,22) contacting with each other as opposed to support the lever member at the upper part. The sheet plates(21,22) are coupled by bent plates. The lower end of the spring lever(31) of the lever member(3) is bent upward to form a protrusion. A number of through-holes are perforated in the sheet plates(21,22).
