A blood pressure monitor cuff is formed by stacking an outer circumferential layer arranged on a side opposite to that of a measurement site and a fluid bladder arranged on the measurement site side. The outer circumferential layer and the fluid bladder are formed of an elastomer material. Two edge portions in a lengthwise direction of the outer circumferential layer protrude in a thickness direction toward the measurement site. The fluid bladder includes a base layer that opposes the outer circumferential layer and a top layer overlapping with the base layer, and the edge portions of the base layer and the top layer are welded together forming a bladder shape. Additional sheets are welded in the thickness direction to the welded edge portions of the top layer and the base layer. The fluid bladder is arranged between the two edge portions of the outer circumferential layer in the width direction.
