To solve the problem in which: when performing simultaneous heating by an induction heating and a halogen lamp, induction current caused by magnetic field occurred in a solenoid coil used as a heating coil for induction heating affects an electric circuit of the halogen lamp.SOLUTION: A thin board heating device 10 using both induction heating and a halogen lamp to raise temperature of the thin steel sheet for heating by using the induction heating and heating with the halogen lamp together comprises: a solenoid type heating coil 12 used as a heating coil for induction heating; even-numbered halogen lamps 16 respectively arranged among a winding shape part 12a of the solenoid coil; and a power source 18 connected to the even-numbered halogen lamps in series, in which the halogen lamps are arranged among the winding shape part of the solenoid coil so that axis of a seal body is parallel with an extension direction of the winding shape part.SELECTED DRAWING: Figure 1 【課題】誘導加熱とハロゲンランプを用いた加熱とによる同時加熱を行う際に、誘導加熱用の加熱コイルとしてのソレノイドコイルで発生する磁界による誘導電流により、ハロゲンランプの電気回路が影響を受けることがないようにする。【解決手段】誘導加熱とハロゲンランプを用いた加熱とを併用して薄板鋼板を昇温して加熱する誘導加熱とハロゲンランプを併用した薄板加熱装置１０において、誘導加熱用の加熱コイルとしてのソレノイド型加熱コイル１２と、ソレノイドコイルの巻き線形状部１２ａの間にそれぞれ配置された偶数本のハロゲンランプ１６と、偶数本のハロゲンランプを直列に接続する電源１８とを有し、ハロゲンランプは、ソレノイドコイルの巻き線形状部の間において、封体の封体軸が巻き線形状部の延長方向と平行となるように配置する。【選択図】図１
