Abstract: An induction heating coil having little high-frequency loss and producing little hast is easily manufactured by covering a conductor with a first insulating material to form a wire, then bundling and twisting such wires to form a stranded wire, covering the outer surface of the stranded wire with a second insulating material to form a coil wire, winding the coil wire a certain number of turns into a coil portion having a certain shape. The end portion of the coil portion and a connecting portion are heated with Joule heat while applying pressure to the end portion at the same time, so that the first and second insulating materials are fused and pressure-bonded to the conductor. Thus a terminal portion for the external connection of the coil portion is fixed while keeping the electrical connection with the conductor. Accordingly, an induction heating coil of low cost and stable quality can be easily manufactured. The induction heating coil producing little heat because of its high-frequency loss and suitable for induction heating of a highly-conductive nonmagnetic substance such as aluminum.

Abstract: An induction heating device is provided that can realize an accrete sensing of the temperature of a to-be-heated object and that is user-friendly. To realize this, the induction heating device includes a sensor for sensing the temperature of the to-be-heated object and can carry out a heating operation only when it is determined that the to-be-heated object exists above the sensor. A display having a circular design and characters for example that shows the position of this sensor is provided on a top plate of the induction heating device.

Abstract translation: 提供一种感应加热装置，其能够实现对被加热物体的温度的感知检测，并且用户友好。 为了实现该目的，感应加热装置具备用于检测被加热物的温度的传感器，仅在判定为在传感器的上方存在被加热物时才能够进行加热动作。 在感应加热装置的顶板上提供具有圆形设计和例如表示该传感器的位置的字符的显示器。
