PROBLEM TO BE SOLVED: To provide a probe holder for opto-biometric measurement preventing a trouble caused by deformation of the probe holder caused by loosening of a fastening component.SOLUTION: The probe holder for opto-biometric measurement includes: a plurality of sockets 2 that hold optical transmission/reception probes 6 and 7 by inserting them into a cylindrical hole 25 of a cylindrical body 22 having a flange part 21 at one end side； a plurality of holder components 11 each including at least two connection holes 14 formed thereon and having flexibility； and a fastening component 4 contacting with the flange part 21 of the socket 2 to clamp the holder components 11. The holder components 11 are connected to each other by the sockets 2 fitted into the connection holes 14 of the holder components 11, where the sockets 2 are supported at a prescribed interval apart from each other, the holder components are rotationally connected thereby within a tangential plane of a measurement object surface to constitute a net-like body. The sockets 2 includes a bamboo shoot-like corrugated surface 23 formed on the outer periphery of the cylindrical body 22, and the fastening component 4 is formed of an annular component with an inside diameter closely fitted with the bamboo shoot-like corrugated surface 23.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2019,JPO&INPIT【課題】締結部品の緩みに起因してプローブホルダの形状が崩れることにより生じる不具合を防止した光生体測定用のプローブホルダを提供する。【解決手段】一端側に鍔部２１を有する筒体２２の筒孔２５に送受光プローブ６、７を挿入して保持する複数のソケット２と、連結孔１４が少なくとも２つ形成され、可撓性を有する複数のホルダ部品１１と、ホルダ部品１１をソケット２の鍔部２１と協働して挟持する締結部品４とを備え、ホルダ部品１１の連結孔１４にソケット２を嵌入してホルダ部品１１を相互に連結するとともに、ソケット２を一定間隔を隔てて支持し、測定対象物表面の接平面内で回動可能に連結されて網状体を構成するとともに、ソケット２には筒体２２の外周にタケノコ状の凹凸面２３が形成され、締結部品４がタケノコ状の凹凸面２３に密嵌可能な内径の環状部品で形成されるようにする。【選択図】図１
