Abstract
A blade holding jig for holding a washer-type cutting blade via an annular retainer flange includes an annular flange holding portion configured to hold a first annular surface of the retainer flange under suction, and an annular non-contact suction portion arranged on an outer peripheral portion of the flange holding portion and configured to produce a negative pressure by ejection of a fluid toward the outer peripheral portion of the retainer flange held by the flange holding portion and to draw up the cutting blade toward the retainer flange. The cutting blade drawn up toward the retainer flange by the non-contact suction portion is held on the retainer flange by a suction force acting from the flange holding portion via a plurality of through holes disposed extending from a second annular surface to the first annular surface of the retainer flange.
