An abutting portion 67 which abuts to contact with a portion which protrudes the most distal end of the distal end surface 12a of the tip 12 of the insertion portion 11 of the endoscope 2 scanning endoscope, scanning endoscope calibration instrument 60 is calibrated a chart 63 which is disposed parallel to the distal end surface 12a by a predetermined distance from the distal end surface 12a of the pattern is drawn, is positioned sites in contact with the portion 67 abutting with the magnitude of the calibration pattern, By having, with a simple configuration, it is possible to accurately calibrate the image scanning endoscope.走査型内視鏡用キャリブレーション器具60は、走査型内視鏡2の挿入部11の先端部12の先端面12aの最も先端側に突出した部位と当接して突き当たる突き当て部67と、較正パターンが描かれ、この較正パターンの大きさに応じて突き当て部67に部位が当接して位置決めされた先端面12aから所定の距離を有して先端面12aと平行配置されるチャート63と、を有することで、簡単な構成により、走査型内視鏡の画像較正を正確に行える。
