A cooking vessel sensor and an induction heating device including a cooking vessel sensor is provided. The cooking vessel sensor may include a cylindrical hollow body having a first receiving space defined therein; a hollow cylindrical magnetic core received in the first space and having a second receiving space defined therein; and a sensing coil wound on an outer face of the side wall by a predetermined number of winding counts. The cylindrical hollow body may have a side wall having a coil outlet defined therein, and the sensing coil may pass through the coil outlet out of the body. The cooking vessel sensor may further include a controller that applies a current to the sensing coil and determines, based on a sensing result of the cooking vessel sensor, whether the cooking vessel is inductive or has an inductive heating property.
