Abstract
A gas detection device includes a flow path in which a gas flows in a predetermined direction, at least one first-type gas sensor that includes a heater for heating the gas, and at least one second-type gas sensor that does not include a heater for heating the gas. The first-type gas sensor is positioned upstream of the second-type gas sensor in the flow path.
