Blood pressure cuff

A blood pressure cuff comprising:

• a band enveloping a fluid bag between a first skin member and a second skin member facing the first skin member;
• a ring-like member held at a position adjacent to one end edge in a longitudinal direction of the band and extending in a lateral direction of the band;
• and
• an auxiliary member stored inside a terminal region between the one end edge in the longitudinal direction of the band and the ring-like member and extending in the lateral direction, wherein
• the ring-like member and the auxiliary member are attached in a state where the ring-like member and the auxiliary member are sandwiched between the first skin member and the second skin member,
• the first skin member and the second skin member are welded or bonded to each other in an adjacent region adjacent to the ring-like member and located on a side opposite to the terminal region with the ring-like member sandwiched between the adjacent region and the terminal region, and in an entire region of the terminal region excluding the auxiliary member,
• the ring-like member is attached in a state where the ring-like member is sandwiched between the first skin member and the second skin member that are welded or bonded in the adjacent region and the terminal region between the auxiliary member and the ring-like member, and
• the auxiliary member is attached in a state where the auxiliary member is sandwiched between the first skin member and the second skin member in the terminal region, the first skin member and the second skin member being welded or bonded in a state of surrounding the auxiliary member entirely, such that rigidity of the terminal region is configured to prevent the terminal region from passing through the ring-like member.
