PROBLEM TO BE SOLVED: To provide a biological information detecting device in which influences of external light can be reduced.SOLUTION: A biological information detecting device 1 comprises: a pulse wave detection part 52 detecting pulse waves of a user; an external light detection part 53 which receives external light and outputs a signal showing a temporal change of a quantity of the received external light as an external light reception signal; and an analysis part (control part 9). The pulse wave detection part 52 has: an irradiation part irradiating a detection part of the user with detection light; and a light receiving part which receives the detection light reflected by the detection part and outputs as a pulse wave signal a signal showing the temporal change of the quantity of light of the detection light emitted. The analysis part uses the external light receiving signal to analyze the pulse wave signal where influences of the external light have been reduced and acquires the pulse wave related information of the user.SELECTED DRAWING: Figure 3 |
