To provide a measuring device, a measuring method, and an electronic device equipped with the measuring device capable of improving biological information measurement accuracy.SOLUTION: A measuring device includes a measuring part for measuring biological information, a control part for controlling the measurement of the measuring part, and a communication part capable of communicating with the outside. When there is a communication to the communication part from the outside during the measurement, the control part determines whether or not the processing on the communication is predetermined processing with a priority higher than the measurement, and if the processing is the predetermined processing, executes control to stop the measurement.SELECTED DRAWING: Figure 1【課題】生体情報の測定精度を向上可能な測定装置、測定方法、および測定装置を備える電子機器を提供する。【解決手段】測定装置は、生体情報を測定する測定部と、測定部の測定を制御する制御部と、外部と通信可能な通信部と、を備える。制御部は、測定の間に通信部に外部から通信があった場合に、通信に関する処理が、測定よりも優先度の高い所定の処理か否かを判定し、処理が所定の処理であれば、測定を停止するように制御する。【選択図】図1
