A method is provided for manufacturing a PTC heating cell with at least one PTC element and contact elements which are made of an electrically conductive material, which are electrically conductively abutted against the PTC element, and which are connected to the PTC element and a corresponding heating cell. In order to improve heat extraction and the connection between the contact element and the PTC element, the contact elements are connected to the PTC element by induction soldering. Also disclosed is a PTC cell in which there is only solder of the solder connection between the thermistor material of the PTC element and the contact element.
