A shape-measuring devicemeasures the shape of a object to be measuredin which segments are arranged and bonded in rows while relatively moving the objectin one direction. The shape-measuring device includes rollersprovided corresponding to the rows of segments and displaced to follow unevenness of an end faceof the object while being rotated on the end facedue to the relative movement, detection meansprovided corresponding to each rollerand detecting the amount of displacement of each roller, and calculation meansfor calculating shape data of the objectbased on the amount of displacement of the rollerdetected by the detection means. The shape-measuring devicecan accurately and promptly measure the shape of the object such as a DPF in which segments are bonded in rows.
