Abstract
A downsized biosensor in which an electrode is formed on one sheet of electrically-insulated substrate, and a sheet of flat substrate is worked three-dimensionally so as to dispose the electrode on the inner side of the substrate to provide a two-dimensional or three-dimensional electrode disposition, whereby a sample introduced by capillary phenomenon can be measured quantitatively in a small space. A production method of a biosensor comprising the steps of bending a plate member so as to position an electrode formed on the surface of the electrically-insulated plane member on the inner side, and disposing the electrode in a space surrounded by a substrate and a cover to thereby form the substrate and the cover from one sheet of plate member.

2. A biosensor, comprising:
-
an electrode disposed in a space sandwiched between a substrate and a cover;
a sample inlet port through which a sample is injected into the space; and
a sample transfer path extending from the sample inlet port to pass through the electrode, wherein the substrate and the cover are formed by folding and bending a sheet of an electrical insulating plate member, the electrode is formed on a surface of the plate member, and the plate member is folded and bent with its surface inside so that the electrode is disposed in the space sandwiched between the substrate and the cover, and the sample transfer path is disposed on the surface of the plate member and is defined by an adhesive layer for face-to-face disposing the substrate and the cover. - View Dependent Claims (3, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 59)

42. A method of producing a biosensor which comprises an electrode, a sample inlet port through which a sample is injected into a space, and a sample transfer path extending from the sample inlet port to pass through the electrode, which are disposed in the space sandwiched between a substrate and a cover, and in which the sample transfer path is defined by an adhesive layer for face-to-face disposing the substrate and the cover,
the method comprises a folding and bending step of a plate member as follows: a step of forming a substrate and a cover from a sheet of an electrical insulating plate member by folding and bending the plate member such that the electrode formed on a surface of the plate member faces inside, to thereby dispose the electrode in the space sandwiched between the substrate and the cover. - View Dependent Claims (43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58)
