A manufacturing method of a ceramic honeycomb structure comprising: a finishing step of finishing one end surface and the other end surface of a cylindrical dried ceramic honeycomb body having the one end surface and the other end surface, to obtain a finished dried ceramic honeycomb body; and a firing step of firing the finished dried ceramic honeycomb body, to obtain the ceramic honeycomb structure, characterised in that in the finishing step, two positions away from each other in a direction from the one end surface toward the other end surface of a peripheral surface of the dried ceramic honeycomb body are a contour measurement start point P1 and a contour measurement start point P2; in a first measuring portion Q1 disposed around a periphery in a circumferential direction including the contour measurement start point P1, a contour of a diametrical dimension of the dried ceramic honeycomb body is measured at a plurality of measurement points while shifting a measurement position from the contour measurement start point P1 in the circumferential direction; in a second measuring portion Q2 disposed around the periphery in a circumferential direction including the contour measurement start point P2, the contour of the diametrical dimension of the dried ceramic honeycomb body is measured at a plurality of measurement points while shifting a measurement position from the contour measurement start point P2 in the circumferential direction; the contour measured at a first measurement point P1x of the first measuring portion Q1 is a contour C1x, the contour measured at a second measurement point P1y present at a position shifted by a predetermined phase from the first measurement point P1x of the first measuring portion Q1 is a contour C1y, the contour measured at a third measurement point P2x of the second measuring portion Q2 which is present at a position of the same phase as the first measurement point P1x is a contour C2x, and the contour measured at a fourth measurement point P2y of the second measuring portion Q2 which is present at a position of the same phase as the second measurement point P1y is a contour C2y; a total of absolute values of differences between respective values of the four contours C1x, C1y, C2x and C2y is obtained for every measurement point; and the one end surface and the other end surface of the dried ceramic honeycomb body are subjected to the finishing step in a state where the four measurement points where the total of the absolute values of the differences between the respective values of the contours C1x, C1y, C2x, and C2y of the peripheral surface of the dried ceramic honeycomb body is minimum are fixed by a first fixture and a second fixture. a finishing step of finishing one end surface and the other end surface of a cylindrical dried ceramic honeycomb body having the one end surface and the other end surface, to obtain a finished dried ceramic honeycomb body;
