A heating magnetic body for a cooking container for an induction range includes a base plate having a bottom exposed to the bottom of a cooking container and elastic support parts, each part having both ends face each other in the base plate and cut off so that the center of each part is upward protruded and both ends being upward bent in such a way as to be connected to the base plate and having a center downward inclined and curved toward both ends, wherein if the cooking container is formed in a mold, when an upper mold corresponding to a lower mold in which the base plate is seated is pressurized, the elastic support parts come into contact with the bottom of the upper mold simultaneously and are elastically supported to reach a top of the bottom of the upper mold B1 after the cooking container is formed.
