Note that a configuration is possible in which partial welded portions with welding margins that are narrower on the long side 107 than on the long side 105 are formed on the air bladder 23 C.
  • the welding margin width of the partial welded portions on the long side 107 is set to be 0.8 mm, and thereby the welding area of the partial welded portions located toward the long side 105 can be made relatively larger than the partial welded portions located toward the long side 107 .
  • the claimed invention is not limited to the above-described embodiments, and combinations of the configurations of the embodiments with each other, and modifications and applications made by a person skilled in the art based on the description of the specification and known techniques are anticipated with respect to embodiments of the claimed invention and encompassed in the range for which protection is sought.
  • the above-described blood pressure information measurement apparatus has been described using a wrist-type blood pressure information measurement apparatus as an example, but one or more embodiments of the claimed invention are not limited to being wrist-type, and one or more embodiments of the claimed invention may have an apparatus configuration that is applicable to any of the four limbs.
  • the blood pressure information measurement apparatus cuff and the blood pressure information measurement apparatus are useful when used in a wrist-type blood pressure information measurement apparatus for measuring blood pressure information such as a blood pressure value in a state of being attached to a wrist of the measurement subject, and can apply a sufficient pressurization force to the measurement site with a simple configuration and realize high-accuracy blood pressure measurement.
