  A heating chamber for storing an object to be heated; a steam generator for generating steam for heating the object to be heated; and a fluid temperature increasing device for heating the steam generated by the steam generator by heat exchange with a heating element. A heating cooker for heating and cooking the object to be heated by supplying the steam heated by the fluid heating device into the heating chamber, and circulating the steam by guiding the steam in the heating chamber to the fluid heating device The fluid temperature raising device includes a first fluid passage through which the steam generated by the steam generator flows, and a second fluid passage through which the steam flowing out of the heating chamber flows, and the second fluid A heating cooker characterized in that the pressure loss of the passage is smaller than the pressure loss of the first fluid passage.   The heating element forms a wall surface of the first fluid passage and forms a plurality of passages or bent passages in the first fluid passage, and the second fluid passage is adjacent to the first fluid passage through the wall surface. The cooking device according to claim 1, wherein the cooking device is a cooking device.   The fluid temperature raising device is wound around an inner cylinder forming a first fluid passage, an outer cylinder surrounding the inner cylinder and forming a second fluid passage around the inner cylinder, and outside the outer cylinder. The heating cooker according to claim 1 or 2, wherein the heating element is electromagnetically heated by applying a high frequency voltage to the coil.   An outer cylinder through which a fluid circulates, a coil wound around the outer cylinder, and an inner cylinder arranged in the outer cylinder and electromagnetically heated by applying a high frequency voltage to the coil, In the fluid temperature raising device for raising the temperature of the fluid flowing in the outer cylinder and the inner cylinder, the pressure loss between the inner cylinder and the outer cylinder is smaller than the pressure loss in the inner cylinder. A fluid temperature raising device.
