Even when a light source having a variable wavelength is used, the illumination density of the illumination light in the image is made uniform to prevent color shift in the superimposed image. A light source unit (6) that repeatedly emits a plurality of illumination lights in different wavelength bands and an insertion unit (5) are provided, and illumination light from the light source unit (6) is emitted from the tip of the insertion unit (5). A light guide section (2) having an exit surface to be driven, and a drive section (4) for two-dimensional scanning of illumination light by reciprocatingly swinging the exit surface in a biaxial direction intersecting the longitudinal direction of the insertion section (5) And a scanning unit including a light source unit (6) and / or a control unit (10) for controlling the driving unit (4) so that the oscillation cycle of the emission surface and the scanning amplitude of the emission surface are proportional to the repetition cycle of the illumination light. A mold endoscope apparatus (1) is provided.波長が可変する光源を用いる場合でも、画像内における照明光の照射密度を均一にし、重畳画像における色ずれを防ぐ。異なる波長帯域の複数の照明光を順番に繰り返し出射する光源部（６）と、挿入部（５）内に設けられ、光源部（６）からの照明光を挿入部（５）の先端から射出させる射出面を有する導光部（２）と、射出面を挿入部（５）の長手方向に交差する２軸方向に往復揺動させることにより照明光を２次元走査させる駆動部（４）と、射出面の揺動周期および射出面の走査振幅が照明光の繰り返し周期に比例するように、光源部（６）または／および駆動部（４）を制御する制御部（１０）とを備える走査型内視鏡装置（１）を提供する。
