A pulse data detecting apparatus, pulse data detecting method and pulse data detection program are provided capable of suppressing an influence of the condition of the body surface to be measured and obtaining an appropriate measurement result under a wide range of conditions. In the present invention, light-emitting elements irradiate a skin surface with light. A light-emission driving section controls lighting-up and the light emission amount of the plurality of light-emitting elements under the control of a CPU. Light-receiving elements each receive reflected light when the skin surface is irradiated by the light-emitting elements, and output a signal. The CPU determines an appropriate combination of light-emitting elements and a light-receiving element(s) based on the output signal from each of the light-receiving elements. A pulse rate calculating section calculates a pulse rate based on the signal outputted from any of the light-receiving elements in the appropriate combination.
