A chemical substance sensing elementfor detecting a specific chemical substance included in biological information includes a carbon nanostructure and, because of metal complex or a fluorescent molecule modifying its surface, exhibits substance selectivity and high sensitivity. Of the substances modifying the surface of carbon nanostructures, CoPc reacts with NO and pentane and DAF-2 reacts with NO, as the components contained in the biological information, respectively, and both produce reaction products. The reaction product derived from CoPc changes electric resistance between nodesand, and the reaction product derived from DAF-2 generates fluorescence of a specific wavelength when irradiated with excitation light. Therefore, by measuring the change in electric resistance or presence/absence and wavelength of fluorescent of the present element, sensing of NO or pentane is possible.

A biochemical sensor capable of detecting a prescribed target substance in a specimen in a short time period with high sensitivity and measuring the amount thereof has a surface and a rear surface, and channels formed from the surface to the rear surface, allowing influx of the specimen. An inner circumferential surface of the channels is formed of porous material. The porous material carries, in its pores, functional substance having a function of forming a reactant by the interaction with the target substance.
