The present invention provides a biological information measuring device capable of generating motivation of exercise. The biological information measuring device includes a setting part (20) for setting a target value relating to exercise intensity; a measurement part (10) for measuring biological information that can be converted to exercise intensity; and a correction part (30) for correcting the target value according to a first measured value relating to exercise intensity, where the first measured value is determined from biological information measured by the measurement part during a first exercise period. When the first measured value is less than a first threshold value, the correction part (30) corrects the targe value as the first measured value. When the first measured value is less than or equal to a second threshold value, the correction part (30) corrects the target value as a second measured value. The measurement part (10) measures a number of sphygmus or heartbeat as the biological information.
