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.

An infrared sensor module includes: an infrared sensor device disposed on a substrate and configured to receive infrared signals; a signal processing circuit device configured to process an output from the infrared sensor device; a metal case which is provided at a predetermined distance from the infrared sensor device, which includes a light incident window provided with an optical system for coupling an image on the infrared sensor device from external infrared signals, and which accommodates the infrared sensor device and the signal processing circuit device; and a sensor cover which is disposed between the infrared sensor device and the case and the signal processing circuit device, and which includes a light-transmitting portion configured to guide the infrared signals entering via the optical system to the infrared sensor device.
