A ferrite device for sensing temperature is disclosed, which is useful for apparatuses such as hot water vessels, fire alarms, and general electronic apparatuses. More specifically, the ferrite device for sensing temperature is manufactured by stack-printing two or more ferrite layers having different Curie temperatures (Tc). Therefore, a mass production is possible with a low manufacturing cost, and control of the process conditions is easy. The temperature sensing ferrite device includes: upper and lower layers composed of a single ferrite material; a plurality of stacked layers stacked between the upper and lower layers and consisting of two or more ferrite subregions; each of the ferrite subregions of one of the plurality of stacked layers has a composition and a shape that are the same as a ferrite subregion in another of the plurality of stacked layers screw type electrodes provided on the respective ferrite subregions.
