An object of the present invention is to provide an infrared detector that is strong against mechanical impacts and enables mounting for various applications to be carried out readily and reliably. An infrared detector 1 includes: a base member 10, positioned at a lower portion; an infrared detecting chip 20, mounted on the base member 10 and for detecting infrared rays; an optical window chip 30, positioned above the infrared detecting chip 20 and for transmitting infrared rays; and bonding wires 38, connecting terminals of the infrared detecting chip 20 with terminals of the base member 10, and a portion below a predetermined distance from an upper surface 30a of the optical window chip 30 is coated by a coating member 40. By interposition of a spacer 36, the optical window chip 30 and the infrared detecting chip 20 form a sealed space 34 that houses an infrared photosensitive portion 23.
