Blood pressure information measurement apparatus cuff and blood pressure information measurement apparatus

A method for manufacturing a blood pressure information measurement apparatus, the method comprising:

• forming a hole in a flexible resin sheet;
• inserting a connecting pipe into the hole;
• overlaying a first end portion and a second end portion of the flexible resin sheet such that an inner side of the first end portion contacts an outer side of the second portion;
• welding a location at which the first end portion and the second end portion overlap to form a first welded portion, such that the flexible resin sheet forms a tube-shaped body having a first end and a second end;
• flattening the tube-shaped body;
• welding the first end and the second to form two second welded portions, such that the tube-shaped body forms a bladder having two long sides and two short sides;
• and
• welding portions of the resin sheet which overlap along a first long side to form one or more first partial welded portions oriented parallel to a wrapping direction of the bladder, wherein a wrapping direction of the bladder is defined as being parallel to a circumference of a body when the bladder is wrapped around the body.
