PROBLEM TO BE SOLVED: To provide a medical connecting member which has a good appearance, has biological safety, and is relatively inexpensive.SOLUTION: The medical connecting member includes: a flexible hollow tube 2 and a joined member 3 in which a through-hole communicated with an inner cavity of the tube is formed. A connecting part 6, in which the tube and the joined member are overlapped by inserting one (insertion body) of the tube or the joined member into the other, includes, along an insertion direction of the insertion body, an adhesion area 31 in which infrared light is applied to an infrared absorption agent supplied between the joined member and the tube, and the joined member and the tube adjacent to the infrared absorption agent are melt, respectively, and are then solidified to join the joined member and the tube mutually, a non-contact area 32, and a contact area 33.COPYRIGHT: (C)2013,JPO&INPIT【課題】本発明は、外観が良好で、生物学的安全性が高く、且つ、比較的安価な医療用連結部材及びその製造方法を提供する。【解決手段】可撓性を有する中空のチューブ2と、チューブに接合され、チューブの内腔と連通する貫通孔が形成された被接合部材3とを含と含み、チューブ及び被接合部材のうちの一方(挿入体)が他方に挿入されることにより、チューブと被接合部材とが重なった連結部6は、被接合部材とチューブとの間に供給された赤外線吸収剤に赤外線を照射して赤外線吸収剤に隣接した被接合部材及びチューブを各々溶融させた後、固化させることにより、被接合部材とチューブとが相互に接合された溶着領域31と、非接触領域32と、接触領域33とを、挿入体の挿入方向に沿って含む。【選択図】図2
