PROBLEM TO BE SOLVED: To provide a connection structure body having a connection structure which facilitates connection between a coil shape member and other components even when a device is very small and does not require heating processing and an adhesive, and also to provide a manufacturing method thereof.SOLUTION: A connection structure body 10 includes: a coil shape member 11； and components connected to the coil shape member. The connection structure body includes: a first component 12 having a helical groove 12a to be screwed onto the coil shape member from one of inner and outer sides； and a second component 13 to be abutted to the coil shape member from the other one of inner and outer sides different from the first component. An area where the first component and the second component are opposed by sandwiching the coil shape member is pressurized at least in a radial direction, so as to be deformed. Then, the coil shape member is fixed to the first component and the second component.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2020,JPO&INPIT【課題】微小な器具であっても、コイル状部材と他部品とを容易に接続でき、加熱処理や接着剤を必要としない接続構造を備えた接続構造体及びその製造方法を提供する。【解決手段】本発明に係る接続構造体は、コイル状部材１１と、コイル状部材に接続された部品とを具備する接続構造体１０であって、コイル状部材に対して内外のいずれか一方側から螺合する螺旋状溝１２ａを備えた第１の部品１２と、第１の部品とは内外の反対側からコイル状部材に当接する第２の部品１３とを有し、第１の部品と第２の部品がコイル状部材を挟んで対向する領域が少なくとも半径方向に加圧されることにより塑性変形され、コイル状部材が第１の部品及び第２の部品に固着されている。【選択図】 図１
