There is disclosed a manufacturing method of a ceramic honeycomb structure in which it is possible to manufacture a ceramic honeycomb structure having an excellent perpendicularity. A contour of an outer diameter dimension of a dried ceramic honeycomb body 50 is measured in a first measuring portion Q1 and a second measuring portion Q2 of the surface of an outer wall 63 of the dried ceramic honeycomb body 50; a total of absolute values of differences between respective values of four contours C1x, C1y, C2x and C2y measured at a first measurement point P1x and a second measurement point P1y of the first measuring portion Q1 and a third measurement point P2x and a fourth measurement point P2y of the second measuring portion Q2 is obtained; and one end surface 61 and the other end surface 62 of the dried ceramic honeycomb body 50 are subjected to finishing step in a state where four measurement points of the outer wall 63 of the dried ceramic honeycomb body 50, at which the total of the absolute values of the differences between the respective values of the contours is minimum, are supported fixed by a first fixture and a second fixture. |
