PROBLEM TO BE SOLVED: To provide a cell for a biosensor capable of conducting accurate measurement, and provided with a high-performance sensor function inherent to a mounted piezoelectric element. SOLUTION: A pair of support springs 6a, 6b joined to an inner wall of a sample chamber 5a via silicon cushioning materials 7a, 7b for filling on an upper surface faced to a sample chamber 5a side out of both upper and lower surfaces of a quartz diaphragm 4 used as a bottom face of the sample chamber 5a of the cell 1 for the biosensor, and adjacent to electrodes 9a, 9b respectively on the lower surface is attached to support the quartz diaphragm 4. A pin hole 11 for air vent from an outside of the cell 1 is drilled in a reservoir chamber 5b faced to the lower surface out of the both upper and lower surfaces of the quartz diaphragm 4 used as a ceiling face of a the liquid leakage reservoir chamber 5b of the cell 1. A plate-like piezoelectric element such as an APT device, an FPW device and an SAW device can be used in place of the quartz diaphragm 4. COPYRIGHT: (C)2004,JPO
