Durability of cutting performance of a fixed blade and a movable blade is increased to downsize a device as a whole and to reduce manufacture costs thereof. The device includes a flat fixed blade ( 21 ), a flat movable blade ( 22 ) having a blade edge allowed to perform horizontal movement with respect to the fixed blade ( 21 ) in directions approaching and departing from a blade edge of the fixed blade ( 21 ), a drive mechanism ( 23 ) for moving the movable blade ( 22 ) with respect to the fixed blade ( 21 ), and spacers ( 28 ) for forming a predetermined gap according to a thickness of a sheet material ( 5 ) between the blade edges ( 21 a) and ( 22 a) in a thickness direction of those when the blade edges ( 21 a) and ( 22 a) of the fixed blade ( 21 ) and the movable blade ( 22 ), respectively, intersect with each other.
