Abstract Translated from Japanese (57)【要約】 【目的】 電磁誘導加熱方式の加熱装置について、励磁 コイルに関する部品コストや組み立てコストを低減化で きるようにすること、コイルの両端折り返し部や安全素 子に起因する部分昇温や部分降温を防止して長手方向に わたる温度分布の均一化が図れるようにすること。 【構成】 導電部材に磁場を作用させて導電部材に発生 する渦電流による発熱で被加熱体を加熱する電磁誘導加 熱方式の加熱装置において、磁場を生成する励磁コイル が基板21の平面上に一層もしくは多層にて形成されて いるシートコイル21aであること。 (57) [Summary] [Objective] For an electromagnetic induction heating type heating device, it is possible to reduce the parts cost and assembly cost related to the excitation coil, and to increase the partial temperature rise due to the folded parts at both ends of the coil and the safety element. Preventing partial temperature drop so that the temperature distribution in the longitudinal direction can be made uniform. In an electromagnetic induction heating type heating device that heats an object to be heated by heat generated by an eddy current generated in the conductive member by applying a magnetic field to the conductive member, an exciting coil that generates a magnetic field is further formed on a plane of a substrate 21. Alternatively, the sheet coil 21a may be formed in multiple layers.
