Abstract
An object of the invention is to obtain a position of each leaf with high accuracy by a configuration that is easy to be manufactured in a multileaf collimator. The multileaf collimator includes a plurality of leaves, and a reflection surface that reflects light emitted from a light source is formed on a peripheral end surface, other than a collimated end surface a, among surrounding end surfaces of the leaf. The peripheral end surface includes a longitudinal end surface d opposite to the collimated end surface a, and an upper lateral end surface b extending from one end of the longitudinal end surface d toward the collimated end surface a. The reflection surface may be a region where the peripheral end surface is subjected to reflection processing.
