PROBLEM TO BE SOLVED: To provide a seismoscope capable of selecting a mounting direction in which a seismic sensor is mounted on a printed circuit board. SOLUTION: The seismoscope has a circuit block A which is contained in a main body 4 and composed of a first printed circuit board 2 having the seismic sensor 1 mounted thereon for sensing the shock of an earthquake, and a second printed circuit board 3 having a plurality of electronic components 30 mounted thereon. A first mounting part 20 and a second mounting part 21 are disposed for mounting the seismic sensor 1 mechanically and electrically on the first printed circuit board 2, and mounting directions in such cases that the seismic sensor 1 is mounted on the first mounting part 20, and the seismic sensor 1 is mounted on the second mounting part 21, are perpendicular to each other.
