A laser processing apparatus includes: a reflection mirror (1, 4) reflecting a laser beam (LA, LB) to an inner or outer surface at an upper edge portion (14a) of a cup (14); a reflection mirror (2, 5) reflecting a part that has passed an outer side of the upper edge portion (14a), of the laser beam (LA, LB) reflected by the reflection mirror (1, 4), to an outer or inner surface of the cup (14); and a rotating pedestal (15) rotating the cup (14) around its center relative to the reflection mirror (1, 4) and the reflection mirror (2, 5). |
