Abstract: The present invention provides a seismic sensor including a housing formed to open one side thereof and having an inner space; a cover for covering the opened side of the housing to seal the inner space and having a rod protruding into the inner space in state that the cover is coupled to the housing; a piezoelectric device disposed in the inner space to generate a voltage when a pressure is applied thereto and for sensing a vibratory ground motion based on change in the voltage; and a mass member disposed between the rod and the piezoelectric device, having a groove, which is formed on an upper portion thereof and into which the rod is inserted to be able to move, and having a pressing member protruding from a lower portion thereof to press the piezoelectric device. Thus, when the vibratory ground motion is generated, the mass member reciprocates along the rod such that the piezoelectric device is pressed. [Reference numerals] (180) Measuring unit
