ABSTRACT:
A gas component detecting element using particles of metal oxide. The particles are prepared and calcined, and then subjected to a treatment which enlarges a specific surface area thereof. Catalyst particles are supported on the surface of these particles, and then the particles are sintered. The gas component detecting element is formed from these particles. A detector formed in this way can be used for a long period of time without any change in characteristics.
