PROBLEM TO BE SOLVED: To provide a hollow needle-like body device having such a simple structure that the hollow needle-like body device is easily and quickly stuck into a region of a skin and reliably injects the entire of the desired amount of an injection liquid into intradermal tissue of the region through through-holes of needle-like bodies without shifting laterally during the sticking, and to provide a method for manufacturing the same.SOLUTION: A hollow needle-like body device includes: a main body 14 having hollow needle-like bodies 12 formed on one surface 14a and having through-holes 12a extending from the another surface 14b to outer surfaces of the needle-like bodies 12 and projections 12b which are provided on peripheral edges of openings on the outer surfaces of the needle-like bodies 12 in the through-holes 12a, respectively, and each have a dimension that is smaller than that of the needle-like body 12. A manufacturing method of the hollow needle-like body device includes: a process of melting a material for the device a process of filling divided molds for the device with the molten material and a process of removing the device formed of the material which is filled in the molds and is solidified, from the molds.COPYRIGHT: (C)2015,JPO&INPIT【課題】皮膚の部位に容易に素早く突き刺せ、この間に横ずれを生じなく所望量の注入液体の全量を確実に針状体の貫通孔を介し前記部位の皮内組織に注入出来る簡易な構成の中空針状体装置及びこのような中空針状体装置の製造方法を提供する。【解決手段】装置は一面14aに中空針状体12が形成され貫通孔12aが他面14bから前記針状体の外表面まで延出した本体14と、貫通孔12aにおいて針状体12の外表面における開口の周縁に設けられた針状体12の寸法よりも小さな寸法の突起12bと、を備えている。製造方法は前記装置の為の材料を溶融する工程と;前記装置の為の分割成形型に前記溶融材料を注入する工程と、前記型に注入され固化した前記材料で形成された前記装置を前記型から取り出す工程とを備えている。【選択図】図2
