  • the electrocardiographic signal detection in the chest a large potential difference can be obtained by arranging the electrodes across the heart, so that the electrode spacing in the non-stretchable belt may be relatively short. Therefore, the heart rate measuring device can be provided with a relatively long stretchable portion, and the length of the strap can be easily adjusted.
  • a biological device such as a heart rate measuring device may be attached to a limb (upper limb or lower limb) using a band.

In this case, after the bio-mounted device is attached to the user by the band, the length of the band does not follow the increase in the diameter (perimeter) of the part where the bio-mounted device is attached, which may cause discomfort to the user. There is.
  • An object of the present invention is to provide a band with electrodes and a biofitting device capable of suppressing causing discomfort to a user when mounted at an appropriate position.
  • the present invention may adopt the following configuration in order to solve the above-mentioned problems.

  • the folded portion is provided between the first elastic portion and the second elastic portion, and is folded back in the ring member so that the first elastic portion and the second elastic portion overlap each other.
  • the joint portion joins the second surface of the first expansion / contraction portion and the second expansion / contraction portion.
  • the longitudinal direction is a direction along the extending direction (circumferential direction) of the band.
