An apparatus and method for continuously producing a cored food in a bar shape by molding a round outer skin material (2) in a space-saving manner provides a method whereby the outer skin material (2) and an inner material (1) are mounted in this order on a carriage conveyor (3). A belt portion comprises a number of belt pieces (31) arranged in the carriage course of the conveyor (3) so that they are foldable towards said conveyor independently from each other. Both end portions (31a) of each belt piece (31) are raised by a pair of guides (4) so as to bend the outer skin material (2) into a gutter-like shape. The outer skin material (2) bent in this way is further compressed with compression molding members (5) through the belt pieces (31). The inner material (1) surrounded with the outer skin material (2) is continuously produced and forms a cored food (F) in a bar shape.
