To provide a biological information measuring device capable of causing a specific light emitting device to emit a light with a high frequency as compared with a case where a plurality of kinds of control signals are output continuously during a non-light emission period of the specific light emitting device.SOLUTION: A biological information measuring device 10A includes; a light emitting device LD1 for irradiating a light of a first wavelength; a control unit 12 for outputting a control signal for controlling light emission of the light emitting device LD1 so as to repeat a light emitting period and a non-light emitting period, and controlling an output period of a plurality of kinds of control signals so that the plurality of kinds of control signals output in mutually different periods in the non-light emitting period are output in such a manner that the respective periods do not continue and the light emitting period is interposed therebetween; and a measuring unit 20 for measuring biological information on a living body using: light that is irradiated from the light emitting device LD1 to the living body, and that transmits the living body or is reflected by the living body; and the control signal of the plurality of kinds of control signals.SELECTED DRAWING: Figure 11【課題】特定の発光素子の非発光期間に、複数種類の制御信号を連続して出力する場合と比較して、特定の発光素子を高い周波数で発光させることができる生体情報測定装置を提供する。【解決手段】生体情報測定装置10Aは、第1の波長の光を照射する発光素子LD1と、発光期間と非発光期間とを繰り返すよう発光素子LD1の発光を制御するための制御信号を出力すると共に、非発光期間において互いに異なる期間に出力される複数種類の制御信号が、互いの期間が連続せず、かつ、発光期間を間に挟んで出力されるよう複数種類の制御信号の出力期間を制御する制御部12と、発光素子LD1から生体に照射され生体を透過又は反射した光と、複数種類の制御信号とを用いて生体の生体情報を測定する測定部20と、を備える。【選択図】図11
