THE CUTTING AND GRINDING APPARATUS INCLUDES A HOLDING TABLE MECHANISM (3) FOR HOLDING THE RECTANGULAR SUBSTRATE (10) AND A PROCESSING UNIT INCLUDING A COMBINED TOOL HAVING A CUTTING BLADE FOR CUTTING THE RECTANGULAR SUBSTRATE (10) HELD BY THE HOLDING TABLE MECHANISM (3) ALONG EACH DIVISION LINE (101) AND A GRINDING WHEEL FOR GRINDING THE CUT SURFACE. THE HOLDING TABLE MECHANISM (3) INCLUDES A SUPPORTING BASE (32) AND A HOLDING TABLE (3) HAVING A HOLDING SURFACE (332) FOR HOLDING THE RECTANGULAR SUBSTRATE (10). THE HOLDING TABLE (3) IS PROVIDED WITH AN INDEX JIG (11) ADAPTED TO BE PLACED ON THE HOLDING SURFACE (332) IN THE CONDITION WHERE THE INDEX JIG (11) IS JOINED THROUGH A WAX (12) TO ONE END SURFACE OF THE RECTANGULAR SUBSTRATE (10).
