A local coil for a magnetic resonance tomography system is provided. The local coil has a plate-shaped local coil body with a main extension plane, and an electronic apparatus within the local coil body. A wireless local coil generates waste heat. Therefore, the local coil has an electrically non-conducting heat sink body that is connected for the conduction of heat to the electronic apparatus, and is configured as a type of plate within the local coil body in order to distribute heat of the electronic apparatus in the main extension plane of the local coil body. This provides that a surface of the local coil has a standards-compliant temperature.
