To enhance precision in measurement of the number of steps even when a walk cycle changes. An acceleration detecting portion outputs a walk signal corresponding to a walk of a user detected by a walk sensor. A step number counting portion of a counting portion counts each signal which is judged to be beyond a first reference cycle range by a walk cycle comparing portion among signals from the acceleration detecting portion as the number of steps for one step, and when an extra-regulation step number processing portion judges that a predetermined number of signals each within a second reference cycle range among the signals each beyond the first reference cycle range is continuously outputted, counts the predetermined number of signals as the predetermined number of steps.
