PROBLEM TO BE SOLVED: To provide a method for manufacturing an infrared sensor, capable of increasing the positioning precision of an optical axis of an infrared lens relative to a cover member. SOLUTION: In fixing the infrared lens 3 onto the cover member 22, a predetermined space region including the infrared lens 3 and the window portion 2a of the cover member 22 is imaged by imaging means 8 with the infrared lens 3 overlapped on the window portion 2a of the cover member 22 in the optical axis direction of the infrared lens 3. Within an image obtained through imaging by the imaging means 8, the particular-portion extraction step for extracting each portion corresponding to each of the opening portion 33 of the anode 32 of the infrared lens 3 and the window portion 2a of the cover member 22 is taken. Moreover, the feature extraction step for determining the center of each portion corresponding to each of the opening portion 33 of the anode 32 extracted by the particular-portion extraction step and the window portion 2a of the cover member 22 is taken. Further, a relative position between the infrared lens 3 and the cover member 22 is adjusted so that both obtained centers meet each other, and the infrared lens 3 is fixed on the cover member 22.
