Disclosed herein are an electrochemical biosensor and a biosensor measuring device. The electrochemical biosensor includes a plurality of electrodes (104,105,107,108), capillary sample cell portions (100), reaction reagent layers, electrode connection portions (106), and a production lot information identification portion (500). The production lot information identification portion (500) is configured such that the production lot information is recorded thereon has one or more infrared absorption/reflection marks, which indicate information about differences between production lots through the printing and/or attachment of colored or colorless materials, having differences in absorbency or reflectivity of infrared rays, in conformity of a predetermined pattern or through the attachment of transparent films. The electrochemical biosensor measuring device includes a plurality of integrated photo-reflector sensing devices (702,703) that emit and receive infrared rays to identify the production lot information recorded on the production lot information identification portion of the biosensor. |
