[ What is claimed is:] [1.] A biosensor comprising an upper plate, a lower plate, a space formed between the two plates for sucking and housing a sample therein, a layer for fixing the two plates together, the space for sucking and housing the sample being partially opened at a peripheral part thereof and partially closed by the layer, a working electrode provided on at least one of the two plates and having at least glucose oxidase and a counter electrode fixed relative to the working electrode, each of the two plates lacking an air vent or hole for connecting to the space,one end of each of the two plates having a tapered part, and a tip part of the working electrode or a tip part of the counter electrode provided on the tapered part. [15.] A biosensor which comprises a lower base, an upper base, a working electrode, an oxidoreductase fixed on the working electrode, and a counter electrode, wherein the working electrode and the counter electrode are fixed on the lower base and the upper base through an adhesive layer so as to have a facing structure, and a lead part for each of the two electrodes is formed in a position of the lower base where an end part thereof is never superposed on the upper base, the electrode on the upper base being conducted to its lead part through the adhesive layer. A biosensor according to claim 15, wherein the conductivity through the adhesive layer is performed by a conductive material provided in a bored part formed in a double-sided adhesive tape. A biosensor according to claim 15, wherein the conductivity through the adhesive layer is performed by a conductive material provided in a bored part formed in the adhesive layer. A biosensor according to claim 15, wherein the conductivity through the adhesive layer is performed by a conductive material filled in bored parts formed in the adhesive layer provided on each of the bases. A biosensor according to claim 15, wherein an oxidoreductase-electron transmitter mixture layer is provided on the working electrode. [39.] A biosensor device which comprises a device body having a connector part, a working electrode and a counter electrode, the connector part having input terminals, a reaction sensor member which is to be inserted into the connector part of the device body in such a manner as to be attachable and detachable, the reaction sensor member having an output terminal of the working electrode and an output terminal of the counter electrode so as to be electrically connected to the input terminals of the connector part when the reaction sensor member is inserted into the connector part of the device body, and wherein a reaction part is formed on at least the working electrode, the reaction sensor member further having a sensor insertion judging electrode, the connector part of the device body having two input terminals, wherein the sensor insertion judging electrode has an output terminal which makes contact with the two input terminals of the connector part, so that the device body is started when the output terminal of the sensor insertion judging electrode becomes in contact with the two input terminals.
