Abstract: In the present invention, a pulse wave signal expressing a pulse is obtained by detecting a pulse of a measurement subject using a pulse wave sensor (S II). The pulse wave signal is stored in a storage unit. A frequency spectrum of the pulse wave signal is found by converting the time-domain pulse wave signal stored in the storage unit into the frequency domain (S 12). It is determined whether or not the measurement subject is at rest by finding a frequency range, within a predetermined total frequency range the pulse rate of a person can take on, in which an intensity of a frequency component of the frequency spectrum exceeds a first threshold, and finding whether or not a percentage of the total frequency range occupied by the frequency range is less than a second threshold (S13). A pulse rate from the point in time when the measurement subject has been determined to be at rest is found as the measurement subject's at-rest pulse rate (S14).

Abstract: An electrode-equipped band includes a first band section and a second band section extending along a longitudinal direction. The second band section includes a first stretchable section, an electrode, a second stretchable section, a ring member, a fold-back section, and a joining section. The first stretchable section has first stretchability along the longitudinal direction. The electrode is provided on a first surface of the first stretchable section. The second stretchable section overlaps with the first stretchable section on a side of a second surface of the first stretchable section, and has second stretchability that allows greater stretch along the longitudinal direction than the first stretchable section. The ring member is provided at a position corresponding to a band end along the longitudinal direction of the second band section, and may be connected to the first band section.
