Abstract
The infrared sensor includes: an infrared sensor chip in which a plurality of pixel portions each including a temperature-sensitive portion formed of a thermopile is disposed in an array on one surface side of a semiconductor substrate; and an IC chip that processes an output signal of the infrared sensor chip. A package includes a package main body on which the infrared sensor chip and the IC chip are mounted to be arranged side-by-side, and a package cover that has a lens transmitting infrared rays and is hermetically bonded to the package main body. The package is provided therein with a cover member that includes a window hole through which infrared rays pass into the infrared sensor chip and equalizes amounts of temperature change of hot junctions and cold junctions among the pixel portions, the temperature change resulting from heating of the IC chip.
