PROBLEM TO BE SOLVED: To acquire a radius measuring implement capable of measuring the radius of a radiused part of an object to be measured with a prescribed accuracy by a simple constitution and by a simple measurement in a method of direct contact with the radiused part. SOLUTION: In the radius measuring implement A, contact surfaces 1sa and 1sa which intersect with each other at right angles and contact surfaces 1sb and 1sb which intersect with each other at right angles are each formed on both sides of a scale main body 1. Gauge heads 2a and 2b are provided for both ends of a measuring member 2 made of a rod slide-freely fitted in a groove at the bottom surface of the scale main body 1. Scales 5a and 5b are displayed on the upper surface of the scale main body 1. Corresponding values in the scales 5a and 5b indicating values obtained by previously converting the amount of movement of a center line of a gauge knob 4 connected to the measuring member 2 from a zero point into the radius of the radiused part are read to easily measure the radius.
