摘要
The nitrogen oxide sensing element of the present invention is such that a sensing film (11) is formed on the surface of a substrate (12a), the sensing film including a polymer containing as dispersed therein a porphyrin containing cobalt as a central metal, or a single derivative having a porphyrin skeleton containing cobalt as a central metal or a mixture of derivatives each having a porphyrin skeleton containing cobalt as a central metal; thus, this sensing element is capable of determining the concentration of NO with high sensitivity and satisfactory accuracy under the condition that the cobalt porphyrin is not affected by reaction inhibitors such as O2 and CO even in the atmosphere.
