A cutting apparatus and a cutting blade is capable of restraining a highly-viscous substance from bending while preventing damage to a blade edge part. A pair of the cutting blades are configured for an approaching/separating movement, and the cutting blades are arranged with blade edge parts facing each other while having thickness directions oriented in the same direction. The cutting blades each have a gradually increasing thickness increased from a blade edge leading end toward a blade root part and have blade edge parts that are offset from one another in the thickness direction of the cutting blades. Each of the cutting blades has a surface in the thickness direction made of a material having a hardness lower than the blade edge part of the other cutting blade.
