BIOSENSOR
First Claim
1. A biosensor which is formed by bonding a first insulating substrate and a second insulating substrate together, and comprises a sample supply port which opens at one ends of the both substrates, to which a sample solution is applied, a capillary communicated with the sample supply port, into which the applied sample solution is introduced by capillary phenomenon, and an air hole which is positioned at an end of the capillary and communicated with air inside the capillary, said supply port, said capillary, and said air hole being formed by the bonding of the both insulating substrates,wherein at least one auxiliary sample supply port communicated with said capillary, through which the applied sample solution is introduced into the capillary, is provided in the vicinity of said sample supply port.

Abstract
It is an object of the present invention to provide an excellent biosensor which can perform supply of a sample solution accurately and easily. A biosensor which has a capillary (7) for collecting a sample solution and analyzes a specific substance in the sample solution is provided with, in addition to an air hole (9), at least two supply ports, i.e., a sample supply port (13) and an auxiliary sample supply port (14), so that supply of the sample solution can be performed from either of the supply ports (13) and (14). Even when the sample supply port (13) is closed up with a fingertip or the like and supply of the sample solution is stopped, the sample solution can be quickly supplied from the other auxiliary sample supply port (14).
