A mobile terminal includes a first fixed-interval timer that counts a first interval; a second fixed-interval timer that counts a second interval longer than the first interval; a motion acceleration detection unit that obtains a first period of acceleration data from an acceleration sensor at the first interval and detects motion acceleration based on the first period of acceleration data; a walking state detection unit that, when the motion acceleration is detected based on the first period of acceleration data, obtains a second period of acceleration data, which is longer than the first period, from the acceleration sensor and detects a walking state or a non-walking state based on the second period of acceleration data; and a continuous walking determining unit that determines that continuous walking is detected when the walking state is detected a predetermined number of times or more within the second interval.
