To provide a user with exercise support information allowing the user to easily recognize the current state of the pulse and to get appropriate exercise for an appropriate period of time.

The exercise support information providing device determines whether the state of exercise of the user is appropriate or not based on whether the pulse rate is within a prescribed target pulse rate range based on the detected pulse rate and the state of change of the pulse rate, and based on whether the rate of increase or the rate of decline of the pulse rate as the state of change of the pulse rate exceeds a prescribed reference rate of increase or decline of the pulse rate. If the rate of increase or decline of the pulse rate exceeds the prescribed reference rate of increase or decline of the pulse rate, the exercise support information providing device announces that the pulse rate will be out of the target pulse rate range in prescribed time (with an icon 71 or icon 73, for example).
