A cutting apparatus comprises a fixing base (50) to which the position of a sealing body (1), i.e., an example of work, is fixed and a nozzle (10) from which abrasive water-jet (2) containing abrasive grains for cutting the sealing body (1) is sprayed out. The fixing base (50) includes a plurality of protrusions (56) and a plurality of bases (57). Each of the protrusions (56) is partitioned by a trench (55) so as to correspond to a plurality of package products (3) after the sealing body (1) is cut and has a through-hole (63) for sucking either the sealing body (1) or the package products (3). Each of the bases (57) mutually connects the protrusions (56) aligned along at least one direction among the protrusions (56). A part of the protrusions (56) or the bases (57) with which the abrasive water-jet collides is formed of a material having hardness higher than that of the abrasive grains.
