Abstract: A cutting apparatus including a pair of blades respectively having linearly extending cutting edges so that the cutting edges are brought into sliding contact with each other to cut a member to be cut which is put between the cutting edges. The cutting apparatus is provided with press members for bringing the sliding contact surface of one of the cutting edges into press contact with the sliding contact surface of the other when the two blades are brought into sliding contact with each other, the press members being disposed along one of the blades. Thus, the sliding contact between the two blades is ensured independently of the rigidity of the blades. Accordingly, it becomes possible to reduce the thickness and increase the length of the blades.
