A shape-measuring device 1 measures the shape of a object to be measured 1 in which segments are arranged and bonded in rows while relatively moving the object 1 in one direction. The shape-measuring device includes rollers 31 provided corresponding to the rows of segments and displaced to follow unevenness of an end face 1 a of the object while being rotated on the end face 1 a due to the relative movement, detection means 35 provided corresponding to each roller 31 and detecting the amount of displacement of each roller 31 , and calculation means 37 for calculating shape data of the object 1 based on the amount of displacement of the roller 31 detected by the detection means 35 . The shape-measuring device 1 can accurately and promptly measure the shape of the object such as a DPF in which segments are bonded in rows.
