Abstract:
1. A biosensor manufacturing method comprising: a sheet material forming process that forms a sheet material with a plurality of biosensor forming sections, each of the biosensor forming sections comprising a first base plate, a second base plate stacked on the first base plate in a thickness direction and forming a capillary between the second base plate and a leading end portion of the first base plate for sucking in sample liquid, and a hydrophilic layer formed on the second base plate at least in a region facing the capillary; and a dicing process to obtain a plurality of biosensors by dicing the sheet material with a blade being inserted from the first base plate side at the leading end of each of the biosensor forming sections so that the leading end face of the first base plate at the capillary side is formed to slope away from the second base plate in the thickness direction after removal of the blade such that the capillary opens onto and widens in the thickness direction leading end portion has a wider opening than the subsequent capillary channel and the leading edge of the second base plate side protrudes beyond the leading edge of the first base plate toward the leading end face of the first base plate and the second base plate.
