GAS MEASUREMENT APPARATUS, MULTIPLE-DEVICE SUBSTRATE, MANUFACTURING METHODS THEREFOR, AND METHODS FOR MANUFACTURING INFRARED LIGHT SOURCE AND PYROELECTRIC INFRARED SENSOR

摘要

This invention provides the following: a gas measurement apparatus, a multiple-device substrate, an infrared light source, and a pyroelectric infrared sensor that can be manufactured via a simple process; and manufacturing methods therefor. The aforementioned gas measurement apparatus has an infrared light source, a sensor, and a gas cell and is characterized in that: the infrared light source has a first upper electrode, a first intermediate layer, and a first lower electrode; and the sensor has a second upper electrode made of the same material as the first upper electrode, a second intermediate layer made of the same material as the first intermediate layer, and a second lower electrode made of the same material as the first lower electrode.
