<p>Disclosed is a cutter (100) equipped with a rotation body (10) and a plurality of cutting sections (1a - 1f) which are provided on a mounting surface (S) that is perpendicular to a rotation axis (A) of the rotation body (10). The cutting sections (1a - 1f) protrude from the mounting surface (S). The cutting sections (1a - 1f) each have a top surface. A cutting blade is formed at least on one side of the top surface. The cutting blade is provided in such a way as to be inclined within a range from 20 degrees to 35 degrees in the rotational direction of the rotation axis (A), provided that a straight line passing through the rotation axis (A) and the end of the cutting blade that faces the rotation axis (A) is taken as a reference line, with the cutting blade seen from the vertical direction with respect to the mounting surface. In the case of the cutter (100) and of a method of machining end faces using the same, it is possible to perform cutting without causing chipping or other damage to film end faces, and it is possible to machine a large number of film end faces.</p> |
