PROBLEM TO BE SOLVED: To provide a pulse wave measuring apparatus which improves accuracy of calculating a pulse wave interval and improves accuracy of evaluating autonomic nerve activity.SOLUTION: A pulse wave measuring apparatus 100 comprises: reference wave extraction means 110 which extracts a reference wave based on a pulse component, from the time-series waveform of a body surface pulse wave measured by a biological signal measurement apparatus 1 emphasis wave extraction means 120 which extracts an emphasis wave from the time-series waveform of the body surface pulse wave, separately from the extraction of the reference wave and pulse wave interval calculation means 130 which identifies the appearance time of the pulse component in consideration of the peaks of both the reference wave and the emphasis wave.SELECTED DRAWING: Figure 4COPYRIGHT: (C)2016,JPO&INPIT
