Abstract

An optoelectronic component includes a radiation side, a contact side opposite the radiation side having at least two electrically conductive contact elements, and a semiconductor layer sequence having an active layer that emits or absorbs the electromagnetic radiation, wherein the at least two electrically conductive contact elements have different polarities, are spaced apart from each other and are completely or partially exposed at the contact side in an unmounted state of the optoelectronic component, a region of the contact side is partially or completely covered with an electrically insulating, contiguously formed cooling element, the cooling element is in direct contact with the contact side and has a thermal conductivity of at least 30 W/(m·K), and in a plan view of the contact side, the cooling element partially covers one or both of the at least two electrically conductive contact elements.
