PROBLEM TO BE SOLVED: To provide a planar induction heating element and an induction heating seamless tubular member which are high in mechanical durability and can perform induction heating with a high heat-generation efficiency.SOLUTION: A planar induction heating element 100 according to the present invention includes a layered nonmagnetic conductive metal region 112 and a layered resin region 111. The layered nonmagnetic conductive metal region 112 mainly includes nonmagnetic conductive metal. The layered resin region mainly includes resin. Further, the layered resin region is located next to the layered nonmagnetic conductive metal region. The planar induction heating element has at least two intersections MP of a dividing line BL between the layered nonmagnetic conductive metal region 112 and the layered resin region 111 and a line SL parallel to a thickness direction in a cross section thereof when viewed through a scanning electron microscope at 1500-fold magnification. |
