PURPOSE: A mounting type endodontic ruler is provided to enable users to easily move an insulator, and to minimize the contact of the ruler with a measuring object. CONSTITUTION: A mounting type endodontic ruler is capable of being mounted on a finger of a user without fixing the left and right directions, and installing a measuring object on the ruler without using a separate supporting unit with the minimum contact. The ruler has 0.5mm unit scales among 1mm unit scales(150) on the upper and lower sides by turns. The scales and letters on the ruler are formed into complementary colors with the surface color.
