PROBLEM TO BE SOLVED: To provide an absorbent article for a surgical operation, a detection device, and a detection method capable of easily performing detection and avoiding substantial increase in cost.SOLUTION: An absorbent article 1 for a surgical operation includes an article body 11 having absorptivity, and an electric conductor 12 attached to the article body 11. A thin wire such as a silver wire and a copper wire with a wire diameter of 0.4-1.0 mm that can be bent and deformed can be used as the electric conductor 12. The electric conductor 12 is provided along an edge 11A of the article body 11, and forms an annular part 13 as a whole. In the annular part 13, one end and the other end of the electric conductor 12 come in contact with each other, and are electrically connected.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2016,JPO&INPIT【課題】容易に検出可能であり、かつ大幅なコストアップを回避可能な手術用吸収性物品、検出装置および検出方法を提供する。【解決手段】 手術用吸収性物品1は、吸収性を有する物品本体11と、物品本体11に取付けられた電気誘導体12とを備える。電気伝導体12として、線径約0.4~1.0mmの銀線や銅線などの曲げ変形可能な細線を用いることができる。電気伝導体12は、物品本体11の縁11Aに沿って設けられ、全体として環状部13を形成する。環状部13において、電気伝導体12の一端と他端とが互いに接触し、電気的に通じる。【選択図】図1
