Provided is a white-cell type non-dispersive infrared gas sensor and more particularly, a non-dispersive infrared carbon dioxide gas sensor deposited with a hydrophobic thin film. To this end, in a carbon dioxide gas sensor for measuring a concentration of carbon dioxide included in gas, the gas sensor is a white-cell type, in the white-cell, first and second reflectorsandare disposed to face a third reflector, a light sourceis provided at one side of the third reflectorand a first detectorand a second detectorare provided at the other side. Further, a first hydrophobic thin filmmay be deposited on the entire reflection surface of the first reflector, a second hydrophobic thin filmmay be deposited on the entire reflection surface of the second reflector, and a third hydrophobic thin filmmay be deposited on the entire reflection surface of the third reflector
