Abstract
A catalyst 1 is provided in a gas passage 4 for communicating between a gas flow-in unit 12 and a gas flow-out unit 13, and the catalyst 1 is heated by a heater 2, and a temperature sensor 3 for detecting the temperature of the heater 2 is provided inside the heater 2. By feeding power to the heater 2, the wall temperature of the heater 2 is raised to heat the catalyst 1, and then malodorous gas containing odor substances is passed in from the gas flow-in unit 12. The malodorous gas passes through the catalyst 1 in the gas passage 4 to be oxidized to be harmless and odorless, and is discharged from the gas flow-out unit 13.
