To provide a measuring device for fruits and vegetables for measuring the bending of an object to be measured in a state close to a human feeling due to the amount of recess on the outer surface of fruits and vegetables and for appropriately measuring the bending regardless of the posture of the object.
An image-processing means for evaluating a long object K to be measured by picking up the image of the object K using a CCD camera and performing the image processing of the image pick-up information obtains a reference line 50 in the longitudinal direction of the object K based on the image pick-up information of the CCD camera, obtains reference points P3 and P4 on a contour where the distance from the reference line 50 can be maximized at each setting region being located at both edge sides in the longitudinal direction of the object K, and evaluates, as the bending Q of the object K, the maximum distance between a virtual line 51 for connecting the reference points P3 and P3 and a contour part located at the virtual line side out of the contours of the object K.
