PROBLEM TO BE SOLVED: To provide a gas detection device capable of reducing a temperature difference of a gas detection unit.SOLUTION: A gas detection device comprises: a gas detection unit 3 including a first substrate 4, a first detection element 1 supported on the first substrate and outputting a first signal according to a detected gas concentration, and a first heater heating the first detection element 1; and a heater control unit 7 arranged on a second substrate 9 supporting the first substrate 4 and controlling the first heater. The gas detection unit 3 and the heater control unit 7 having an approximately square shape on the second substrate 9 are arranged on a first straight line orthogonal to one side of the heater control unit 7.SELECTED DRAWING: Figure 1 |
