PROBLEM TO BE SOLVED: To provide an alarm clock of an alarming effect reduced in habituation, as an alarm stopping function for the alarm clock is sometimes habituated to reduce the alarming effect in a conventional method wherein a predetermined operation is applied to an operation part. SOLUTION: This alarm clock capable of indicating an alarm stopping method determines the different alarm stopping method every time at random by an internal arithmetic unit, and conducts operations several times. When an indicated operation is mistaken, the next operation is not indicated, and confirmation-operations are repeated. The habituation is prevented by changing the alarm stopping operation every time, and the operations indicated by the internal arithmetic unit are repeated to stimulate wake-up.
