A cutter (370) includes a male blade (371), a female blade (372), an advancement and retraction controller (373) and a suction device (374). The male blade (371) includes: a linear cutting portion (3711) linearly shaped with a predetermined thickness in a center part; a rounded cutting portion (3712) where a radius (R) having a substantially arc shape in planar view is continuously formed from the linear cutting portion (3711); and an end (3713) provided adjacent to the rounded cutting portion (3712). The female blade (372) has a fitting portion (3721) that is a hole conforming to the profile of the male blade (371) in planar view and to which the male blade (371) is fitted. On a lateral side of the female blade (372), an elongated hole for inserting a base film from one lateral side to the other lateral side is formed as an insertion portion (3722). |
