PROBLEM TO BE SOLVED: To provide a method for producing an insertion aid which is excellent operability and easy processing.SOLUTION: An insertion aid 60 having a tip end face, a base end face and an outer periphery face comprises a multilumen tube formed by penetration from the tip end face to the base end face with an insertion pathway 70 in which an insertion section 12 of an endoscope 10 is inserted and fluid conduits 72 and 74 which are formed apart from the insertion pathway 70. Openings 80 and 90 are formed on the outer periphery face to connect the conduits 72 and 74 which are closed at the tip end face side rather than the openings 80 and 90.COPYRIGHT: (C)2012,JPO&INPIT【課題】操作性が良く、加工が簡単な挿入補助具の製造方法を提供する。【解決手段】本発明の挿入補助具60は、先端面と基端面と外周面とを有し、内視鏡10の挿入部12が挿通される挿通路70と挿通路70とは別に形成された流体の管路72、74とが先端面から基端面まで貫通形成されたマルチルーメンチューブから成り、管路72、74に連通するように外周面に開口80、90が形成され、管路72、74は開口80、90よりも先端面側で閉塞される。【選択図】 図6
