Abstract

A biosensor that can perform analysis based on a sample noninvasively collected from a human body is provided. The biosensor comprises an identification substance (38) that binds to a substance to be detected (40), and an electrode (16) charged with a charge of the identification substance (38), comprises an inhibitor (39) that inhibits a substance not to be detected (42) from attaching to at least one of the identification substance (38) and the electrode (16), and detects a change in a charge density of the electrode (16) caused by binding of the substance to be detected (40) to the identification substance (38).
