    Abstract: A high sensitive infrared detector for an NDIR gas sensor and a manufacturing method thereof are provided to reduce process time by bulk etching an upper part of a substrate. A high sensitive infrared detector for an NDIR gas sensor comprises a substrate(210) having a supporting layer(230) formed on at least one side, an insulating layer(250) formed on the supporting layer, and a groove formed on the upper part of the substrate. The groove has a detection part on its upper side and a supporting part for supporting the detection part, wherein the detection part and the supporting part include an electrode pattern(253) formed on the insulation layer and a protective layer pattern(270) formed on the electrode pattern. The detection part has a reflection layer pattern(235) formed on the supporting layer inside the insulation layer, and a detection layer pattern(255) formed on the insulation layer in the protective layer pattern to be connected to the electrode pattern.
