PROBLEM TO BE SOLVED: To solve such a problem that, when a temperature change occurs in a piezoelectric actuator, it is impossible to inhibit a change in characteristics of the piezoelectric actuator.SOLUTION: An optical scanning type endoscope comprises: an optical fiber exiting light from an exit end an oscillation member that is adhesively fixed to a part of a tip end of the optical fiber and oscillates the exit end so as to scan the light exited from the exit end at a prescribed trajectory a support member that supports the oscillation member and is disposed to enclose the oscillation member and a first heat generating element provided inside the support member for controlling the temperature of the support member. This configuration can control the temperature of the support member so as to control the temperature of the oscillation member.COPYRIGHT: (C)2015,JPO&INPIT【課題】圧電アクチュエータに温度変化が生じた場合に、圧電アクチュエータの特性の変化を抑えることができない。【解決手段】射出端より光が射出される光ファイバと、光ファイバの先端部の一部に接着固定され、射出端より射出された光を所定の軌跡で走査するように射出端を振動させる振動部材と、振動部材を支持し、振動部材を囲うように配置された支持部材と、支持部材の内部に設けられ、支持部材の温度を制御するための第1の発熱素子と、を備える構成を提供する。この構成において、支持部材の温度が制御されることにより、振動部材の温度が制御される。【選択図】図2
