To provide a groundwater pressure measuring device capable of accurately measuring not only the static hydraulic pressure of groundwater, but also a dynamic hydraulic pressure of the groundwater which varies by propagation of vibrational energy.
The groundwater pressure measuring device A includes a hydraulic pressure measuring probe 2 which is inserted into a drilled hole 4 drilled underground to measure the hydraulic pressure of the groundwater. The measuring probe 2 is formed by providing a static pressure measuring sensor (hydraulic pressure sensor) 7 for measuring the static hydraulic pressure of the groundwater, and a dynamic pressure measuring sensor (hydrophone) 8 for measuring the dynamic hydraulic pressure of the groundwater which varies by the vibrational energy propagated underground.
