ABSTRACT:
An object of the present invention is to provide a highly sensitive Langevin type quartz sensor which is easy in assembling, is less likely to cause damage to a quartz resonator during the assembly work, and is easy to perform a measurement work. As a specific means to solve the problem, a recess is formed in a quartz holding member made of, for instance, rubber, and an airtight space is formed by holding the quartz resonator with the quartz holding member so as to cover the recess. In the meantime, a hole is provided in a circuit board and a projected portion which projects toward back side of the recess in the quartz holding member is fitted into this hole. Then, a resonator electrode of the quartz resonator and an electrode of the circuit board are electrically connected using a conductive adhesive, a pouring space for a sample solution is formed by pressing a position surrounding the quartz resonator in the quartz holding member toward the circuit board side with a lid so that the quartz sensor is structured. Since there is no possibility for such a quartz sensor that the quartz resonator is directly pressed and an excessive force is applied to the quartz resonator during manufacturing and the quartz resonator is not in direct contact with the circuit board, damage to the quartz resonator is suppressed.
