A biological information measuring device includes: a biological information measuring unit for measuring biological information of a user a motion signal output unit for outputting a motion signal corresponding to motion of the user and a control unit.The control unit causes the biological information measuring unit to measure the biological information when amplitude of the motion signal is smaller than a first setting value during a first period and causes the biological information measuring unit to stop measurement when the amplitude is greater than the first setting value during a second period and there is a period where the amplitude is greater than a second setting value, which is greater than the first setting value, in the second period.
