To provide a pedometer having a pitch generating function which is simpler and is not troublesome.

Ideal pitch sounds for indicating an ideal walking pitch are generated for a specified period of time by an ideal pitch generating means 1, and a real walking pitch is measured by a walking pitch measuring means 2. Real walking pitches being out of standard are excluded by an out-of-standard walking pitch excluding means 3. From a deviating state from the ideal walking pitch of a real walking pitch measured after ideal pitch sounds have stopped, announcement information is judged by a deviating state judging means 4, and the judged announcement information is reported by a deviating state reporting means 5. Besides, it is evaluated as history information also in a history evaluating means 6.
