An objective is to provide an image predictive encoding device, image predictive encoding method, image predictive encoding program, image predictive decoding device, image predictive decoding method, and image predictive decoding program for selecting a plurality of candidate prediction signals, without increase in information amount. The medical device lead includes a lead body, an electrode shaft, and a tip electrode. There is a difference in level between the first surface and the second surface, so that the second surface is located farther from the top pole layer than the first surface.
