An induction heating device comprising a temperature sensor provided in boards on which heating coils are patterned. The induction heating device comprises: a top plate on which a cooking container is to be placed; a heating coil board formed by pressing stacked boards including a plurality of heating coil pattern layers on which heating coils are printed and patterned, and an insulating layer which respectively insulates and bonds corresponding heating coil pattern layer among the plurality of heating coil pattern layers; and a temperature sensor, including two leads, arrangeable in a hole formed to pass through the heating coil board, the temperature sensor to sense the temperature of the top plate or the cooking container placed on the top plate, the temperature sensor is arranged such that the two leads are soldered to at least a portion of the heating coil board without requiring a wire.
