Abstract
To provide a quartz sensor capable of detecting a sensing target with high sensitivity also in measurement in a liquid phase in which a difference in Q values at the time of measurement in the liquid phase and in a vapor phase is small. In a quartz sensorincluding an AT-cut quartz platehaving a capture layer (absorbing layer)formed on one surface (XZ' surface) thereof and detecting a sensing target based on an amount of change in a frequency of a quartz resonatorcaused when the sensing target is absorbed by the capture layer, there are formed electrodesfor oscillating the quartz plateon end faces (XY′ surfaces) mutually opposite in a Z′ direction of the surface of the quartz resonatoron which the capture layeris formed (XZ′ surface).
