Abstract
To provide an auxiliary plate and a processing device that can suppress the occurrence of damage to a surface of a sheet member such as a corrugated cardboard with a large thickness. An auxiliary plate includes a plate body with a flat-plate shape, and a cutting-blade contact portion provided on a surface of this plate body at a position opposed to a cutting blades arranged in the stamping die, so as to protrude from the surface, while including a contact surfaces with a width dimension greater than a thickness of the cutting blade. The contact surface of the cutting-blade contact portion is chamfered at both edges in its width direction.
