[Problems] To provide a sprinkler head installed by burying it in a ceiling, having a cover plate to conceal the sprinkler head, enabling the adjustment of the height of the sprinkler head relative to the surface of the ceiling, and capable of efficiently transferring the heat of flame absorbed by the cover plate to the heat sensitive body of the sprinkler head. [Means for Solving Problems] A heat collector ( 15 ) having a plurality of fins ( 14 ) in the radial direction is fitted to the heat sensitive body of the sprinkler head, and the fins ( 14 ) are bent in a diagonal lower side by a plurality of bent parts ( 16 ). A disk-like heat collector ( 13 ) is stackingly installed on the upper part of the heat collector ( 15 ), and ribs ( 13 A) and ( 13 B) formed on the heat collector ( 13 ) are installed at positions where the bent parts ( 16 ) are not interfered with the ribs ( 13 A) and ( 13 B) when the heat collector ( 15 ) is contracted.
