Abstract: A heater for an ingot growing apparatus is provided. The heater, disposed outside a crucible so as to heat the crucible, for an ingot growing apparatus comprises: a body part including a flow path through which a heat source, for generating heat for heating the crucible, flows; and a heat increasing part formed by being inwardly cut at a predetermined depth along a circumferential direction at an upper side of the body part, wherein a portion of the body part, at which the heat increasing part is formed, has a thickness (d3) formed to be less than a thickness (d2) of the other portion of the body part such that the heat can be intensively generated at the heat increasing part.
