Abstract
An infrared light source includes a resistor formed on the side of one principal surface of a support substrate via an insulating film; a plurality of projections formed on the one principal surface side of the support substrate by etching the support substrate; and a protection film stacked as a layer on top of the resistor and projections. The resistor is disposed on the same plane in a region which forms an infrared emission portion in which the plurality of projections and the resistor are formed, and infrared is efficiently emitted from the region in which are formed the projections by heat generated by energizing the resistor.
