Abstract
A gas sensing device comprises a gas sensing element comprising a gas-sensitive resistive film formed of an aggregate of ultrafine particles of a suitable material deposited on the surface of a substrate of an electrical insulator formed with electrodes. In a method of manufacturing such a gas sensing device, a gas-sensitive material is evaporated in a gas atmosphere to provide the gas-sensitive resistive film of ultrafine particles of the material.
