The invention discloses a far-infrared planar heat generator and a production method thereof. The far-infrared planar heat generator comprises a heat generating substrate, an upper insulating heat conducting layer disposed at the upper end of the heat generating substrate, and a lower insulating heat conducting layer disposed at the lower end of the heat generating substrate, wherein the electrodes are disposed on both ends of the heat generating substrate; the heat generating substrate, the upper insulating heat conducting layer and the lower insulating heat conducting layer are each a sheet-like structure; the heat generating substrate is formed by mixing graphene powders, nano-scale carbon powders and nano-scale PI powders at high temperature and high speed and then tape casting the same; the upper insulating heat conducting layer and the lower insulating heat conducting layer are both composed of pure PI films; the heat generating substrate and the upper insulating heat conductinglayer are laminated into
