PROBLEM TO BE SOLVED: To provide a pulse wave propagation time measurement device capable of measuring pulse wave propagation time more accurately.;SOLUTION: A pulse wave propagation time measurement device according to one aspect of the present invention comprises: a belt unit; a plurality of first electrodes and a plurality of second electrodes provided on the inner peripheral surface of the belt unit; a third electrode provided on the outer peripheral surface of the belt unit; a first electrocardiographic signal acquisition unit which acquires a first electrocardiographic signal of a user by using the plurality of first electrodes; a second electrocardiographic signal acquisition unit which acquires a second electrocardiographic signal of the user by using the second electrodes and the third electrode; a feature amount parameter calculation unit which calculates a feature amount parameter pertaining to a waveform feature point of the first electrocardiographic signal on the basis of a waveform feature point of the second electrocardiographic signal; a pulse wave signal acquisition unit which includes a pulse wave sensor provided on the belt unit, and acquires a pulse wave signal representing the pulse wave of the user by using the pulse wave sensor; and a pulse wave propagation time calculation unit which detects a waveform feature point of the first electrocardiographic signal by using the feature point parameter, and calculates a pulse wave propagation time on the basis of the time difference between the detected waveform feature point and the waveform feature point of the pulse wave.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2020,JPO&INPIT
