Abstract: There is provided a system capable of estimating biological data such as a pulse at the time of walking (exercise) with good reproducibility. Biological data at the time of walking is estimated indirectly by acquiring a relationship between biological data and exercise stress levels in body burden capacity acquiring means 21 prior to walking, acquiring an exercise stress level at the time of walking in means 22 for acquiring an exercise stress level at the time of walking, and relating the exercise stress level at the time of walking to the relationship between biological data and exercise stress levels in means 23 for estimating biological data at the time of walking. Further, a walking amount is also computed by use of the biological data at the time of walking in walking amount computing means 24.
