PROBLEM TO BE SOLVED: To solve the following problem of a conventional measuring cell configuration by a QCM sensor device: because it is necessary to separately provide a reference electrode and a counter electrode and to control positions thereof, it becomes costly and its size is increased, and an adhesive between a crystal substrate and a support substrate is dissolved out according to a sample when exposing the crystal substrate to the sample. SOLUTION: In this QCM sensor device, the crystal substrate 31 is integrally provided with the reference electrode 35 and the counter electrode 34 in addition to a working electrode 33A and a rear face electrode 33B thereof. Only a working electrode portion is provided with a sample reservoir around a face exposed to the sample. COPYRIGHT: (C)2005,JPO&NCIPI
