1. A method of heating a dispersion composition, comprising the step of scanning a beam spot of a laser beam while irradiating a composition having a linear closed curve shape and comprising a dispersoid and a disperse medium having a lower boiling point or a lower decomposition temperature than the dispersoid, with the laser beam,wherein a shape of the beam spot is a rectangle,wherein the scanning is performed while a minor axis of the beam spot is tilted relative to the scanning direction,wherein the scanning with the tilted laser beam is performed along the closed curve shape, andwherein the beam spot is scanned while each of two opposite sides of the beam spot intersects with opposite edges of the composition.
