Abstract
A biosensor is capable of preventing a sample from flowing out of the air hole to the outside with superior accuracy. The biosensor includes: a first substrate having an air hole; and a second substrate, the first and second substrates being laminated on each other, wherein the biosensor has a sample flow path between the first and second substrates, in a sample flow direction in the flow path, an upstream end of the flow path is in communication with a sample introduction port, and a downstream end of the flow path is in communication with the air hole, an upper surface of the flow path is formed of a surface of the first substrate facing the second substrate, and a region on the introduction port side of the upper surface of the flow path is a hydrophilic region, and a region on the air hole side of the upper surface of the flow path is a water-repellent region.
