1. A blood pressure measurement device comprising:
a curler curving in such a manner as to follow along a circumferential direction of a portion of a living body where the curler is configured to be attached; and
a cuff including one or a plurality of bag-like structures stacked on one another and a bonded portion being bonded to the curler, each of the bag-like structures including two sheet members formed of resin materials and welded together, and configured to be inflated with a fluid, and the bonded portion being integrally provided on one of the two sheet members of the bag-like structure disposed on a curler side, the bonded portion having a higher bending strength than the bag-like structure disposed on the curler side,
wherein the bonded portion includes
a first member having a higher bending strength than the one of the two sheet members of the bag-like structure disposed on the curler side, and
a second member integrally formed with the first member and integrally welded to the one of the two sheet members of the bag-like structure disposed on the curler side,
wherein the first member is smaller than the second member and positioned between the second member and the one of the sheet members, and
wherein an edge portion of the second member is welded to an edge portion of the one of the two sheet members of the bag-like structure disposed on the curler side with the first member, which is smaller than the second member, being covered with the second member.
