The invention relates to an induction cooker composite ceramic panel and a manufacturing method thereof. The induction cooker composite ceramic panel comprises a high-thermal-conductivity ceramic panel, magnetic heating materials and a ceramic bottom panel from top to bottom in sequence, wherein the lower surface of the high-thermal-conductivity ceramic panel is coated with the magnetic heating materials. The induction cooker composite ceramic panel can be applicable to an induction cooker for heating various pots. The high-thermal-conductivity ceramic panel at the upmost layer is excellent inthermal conductivity and can efficiently transmit heat to pots. The ceramic bottom panel at the lowest layer is low in thermal conductivity and effectively prevents heat generated by the magnetic heating materials from being transmitted to a coil and other electronic devices at the lower layer, and therefore the service life of the induction cooker is prolonged. Meanwhile, the problems that pot explosion is caused by low heat matching between the bottom of a common ceramic pot and the magnetic heating materials and a ceramic inner container with a magnetic heating material coating is prone toabrasion and cracking are avoided, and the pot material range of the induction cooker is widened. A magnetic heating sizing agent printing process facilitates batch production.
