PROBLEM TO BE SOLVED: To allow a magnet separated from an initial position by being moved by horizontal vibration of an earthquake or the like to be restored to the initial position after detecting the earthquake. SOLUTION: This vibration-sensitive breaker is provided with: a case 6 with a tube 2 formed at its center; a reed switch 1 installed in the tube; a magnet 3 installed in the case for changing an operation state of the reed switch by moving; a non-magnetic body 4 installed in contact with the magnet in the case for setting the initial position of the magnet; a magnetic body 5 for keeping the magnet at the initial position; and a reset member for determining a distance for the magnet to move from the initial position and for restoring the magnet to the initial position. The reset member comprises: an opening 11 formed on the other end side of the case; and a reset button 9 capable of entering into and exiting from the opening and having a retaining member 9a locked to an opening edge of the opening.
