A cutter for cutting a continuous corrugated strip includes a feed gear, on the outer circumference of which a tooth portion engaging with a continuous corrugated strip such as a corrugated fin used for a radiator is provided, wherein a tooth cutout portion is formed in the feed gear. In a cavity formed in the feed gear, a first cutting blade unit rotated around an eccentric center is accommodated. When a first cutting blade radially provided in the first cutting blade unit is projected from the tooth cutout portion, the first cutting blade comes into contact with a second cutting blade provided outside, so that the continuous corrugated strip can be cut.
