Abstract:
1. A heating apparatus comprising: heating elements arranged of a sheet form and having notches or through holes provided therein; a side wall member made of an electrically conductive material and arranged to surround and define the heating space; holding members disposed at the heating space side of the side wall member for holding at one end the heating elements; and extending members, each member comprising an extending-through portion arranged to project from the heating space side of the side wall member and extend through the notch or through hole between both ends in the heating element and projected portions arranged to project at both, front and back, sides of the heating element from the extending-through portion in a direction, which is orthogonal to the extending direction of the extending-through portion, thus to inhibit the displacement of the heating elements along the extending direction.
