Induction heating device of metal sheet, metal sheet processing equipment, and induction heating method of metal sheet

An induction heating device for a metal sheet comprises: a first conductor component, facing at least one side of the front and the back of the metal sheet, and spanning across the metal sheet in the width direction; a second conductor component, separated from the first conductor component in an over-sheet direction of the metal sheet by a first distance, and facing at least one side of the front and the back of the metal sheet and spanning across the metal sheet in the width direction; a connecting component, connecting the first conductor component and the second conductor component to each other to form a first secondary closed loop at a position where the ends of the metal sheet in the width direction are separated; and an AC power source connected to the first secondary closed loop, wherein the first distance is greater than the sum of the sizes of the first conductor component and the second conductor component in the over-sheet direction of the metal sheet. According to the present disclosure, even if
