Cutting apparatus

A cutting apparatus comprising:

• a placing table on which a workpiece formed in a plate shape is placed;
• a first workpiece pressing portion configured to press a first workpiece region of the workpiece toward the placing table;
• a second workpiece pressing portion provided to be separated from the first workpiece pressing portion in an extending direction of the workpiece and configured to press a second workpiece region of the workpiece toward the placing table;
• and
• a blade portion configured to move up and down in a predetermined direction corresponding to a thickness direction of the workpiece between the first workpiece pressing portion and the second workpiece pressing portion to cut the workpiece, wherein
• the blade portion includes
• a first blade surface extending in the predetermined direction from a distal end of the blade portion and facing the first workpiece pressing portion, and
• a second blade surface extending along the second workpiece pressing portion from the distal end of the blade portion and facing the second workpiece pressing portion,
• the cutting apparatus further comprises:
• a blow part configured to supply a blow gas to a region around the distal end of the blade portion through a gap between the first blade surface and the first workpiece pressing portion;
• and
• a suction part configured to suck a gas in the region around the distal end of the blade portion through a gap between the second blade surface and the second workpiece pressing portion.
