A sensor support device for liquid phase leak detection test of a storage tank is provided to prevent external vibrations from interfering with the leak detection test by fixing a monitoring hole and a leak detection sensor by elasticity of synthetic resin. A sensor support device for liquid phase leak detection test of a storage tank comprises a sensor contact part(1.1,1.2), a fixing wing part(2), and a pressure transmission part(3). The sensor contact part, making contact with a pipe-like sensor(4) to fix the sensor with the sensor support device, includes a wing opening projection(1.3) on its lower side. The cylindrical fixing wing part includes four wings(2.1) on its lower side, which are expanded by the wing opening projection due to the pressure exerted from the pressure transmission part so as to fix the sensor to a monitoring hole(5). The ring-shaped pressure transmission part, whose inner periphery is threaded, firmly secures the wings of the fixing wing part to the monitoring hole.
