A high heat-radiating structure of a gas sensor is provided. The gas sensor includes a sensing element which is to be exposed to a measurement gas and a body in which the sensing element is installed. The body has an outer wall which includes a gas-exposed surface and an air-exposed surface. The gas-exposed surface is to be exposed to the measurement gas. The air-exposed surface is to be exposed to an atmospheric air. At least a portion of at least one of the air-exposed surface and the gas-exposed surface has an emissivity of 0.7 or more, thereby enhancing the heat radiation from inside to outside the body of the gas sensor to protect less heat resistant parts from thermal damage.
