PROBLEM TO BE SOLVED: To provide an optical scanner capable of obtaining desired scanning characteristics.SOLUTION: An optical scanner comprises: optical fiber 100 a tube member 110 for passing the optical fiber 100 actuators 120a to 120d for giving vibration to the optical fiber 100 and a holding member 130 for forming a node of the vibration on the optical fiber 100. At least a part of the holding member 130 is fixed to the tube member 110. The optical fiber 100 is held by friction force to the holding member 130.COPYRIGHT: (C)2015,JPO&INPIT【課題】所望の走査特性が得られる光走査装置を提供する。【解決手段】光ファイバ100と、光ファイバ100を通すチューブ部材110と、光ファイバ100に振動を与えるアクチュエータ120a~120dと、光ファイバ100に振動の節を形成する保持部材130と、を備え、保持部材130は少なくとも一部がチューブ部材110に固定され、光ファイバ100は保持部材130に摩擦力で保持される。【選択図】図1
