ABSTRACT:
It is an object of the present invention to provide a technique that can realize improvement of sensitivity of a vibrator. A platform50to which a substance adheres or sticks is provided to be mechanically coupled to a vibrator20of a sensor via bridges51. Sensitivity of the sensor is improved by causing the mass of a substance adhering or sticking onto the platform50as if the substance concentratedly adheres or sticks to places where the platform50is connected to the vibrator20. It is preferable to connect, via the bridges51, the platform50to places where the platform50vibrates integrally with the vibrator20. For this purpose, it is preferable to mechanically couple, via the bridges51, the platform50to regions where vibration occurs only in one of an r direction or a θ direction in the vibrator20.
