さに形成されている。When a plurality of the spacers S are fitted to the rising peripheral edge portion 5 at required intervals, both side end portions P of the short piece portion 10 of the heater member 1 are formed as shown in FIGS. It is formed in such a size that it abuts on the inner peripheral surface of the outer peripheral edge portion and maintains a constant gap a between the rising peripheral edge portion 5 and the outer peripheral edge portion 4 of the heater member 1.

Since the contact with the peripheral surface is in a so-called "point contact" or "line contact" state, the boiling water or the like is not sucked from the gap b toward the opening 3 side due to a capillary phenomenon. Needless to say, the action of sucking broth or the like due to the capillary phenomenon does not occur in the gap a having a larger gap width than the gap b.
尚、上記実施例では、この考案を電気こんろに適用し

めることができるため安全である等の効果を奏する。In the electric heating device according to the present invention, as described above, the gap between the outer peripheral edge of the heater member and the rising peripheral edge of the opening to which the heater member is mounted is made uniform by the spacer having a simple structure. Since it is configured so that the rising peripheral edge of the opening and the outer peripheral edge of the heater member do not come into close contact with each other, boiling water or the like may enter the main body of the hob due to capillary action and stain the members inside the main hob. Corrosion can be surely prevented, and the heat from the heating member transmitted to the top plate can be made uniform to enhance the heat radiation effect.
