PROBLEM TO BE SOLVED: To provide a sphygmomanometer which is configured to appropriately compress an airbag relative to an upper arm and easily make close contact with the upper arm, and to provide a method of manufacturing the same.SOLUTION: The sphygmomanometer 10 includes an arm band 12 and a body 16. The arm band 12 includes a cylindrical housing 30, the airbag 32 provided inside the housing 30 for compressing the upper arm of a subject which is inserted into the inside, and four folding lines 52a-52d which extend in an X direction where the upper arm is inserted on the inner circumferential surface 40a of the airbag 32, are thinner than the other parts, and have different hardness. The folding lines 52a-52d are configured to be thin compared to the other parts. The folding lines 52a-52d are formed by heating by a high-frequency welding machine. The body 16 has pressurizing means 18 for supplying air to the airbag 32.COPYRIGHT: (C)2010,JPO&INPIT【課題】空気袋を上腕に対して適切に圧迫する。センサを上腕に密着しやくする。【解決手段】血圧計10は、腕帯12と本体16とを有する。腕帯12は、筒状のハウジング30と、ハウジング30内に設けられ、中に挿入された被測定者の上腕を圧迫する空気袋32と、空気袋32の内周面40aで、上腕が挿入されるX方向に延在し、他の部分よりも薄肉で硬さが異なる4本の折り目52a~52dとを有する。折り目52a~52dは、他の部分と比較して薄肉構成である。折り目52a~52dは、高周波溶着機によって加熱形成されている。本体16は、空気袋32に対して空気を給気する加圧手段18を有する。【選択図】図2
