| Zusammenfassung: | PROBLEM TO BE SOLVED: To make a current path in a planar heating element more likely to be blocked when the planar heating element is overheated.SOLUTION: A heating device comprises: a planar heating element which generates heat by current flowing therein; and an application part which applies tension to the planar heating element in a cross direction which crosses a thickness direction of the planar heating element.SELECTED DRAWING: Figure 4
【課題】面状発熱体が過熱した場合に面状発熱体における電流経路が遮断されやすくする。【解決手段】加熱装置は、自らに電流が流れることで発熱する面状発熱体と、前記面状発熱体に対して該面状発熱体の厚み方向と交差する交差方向に張力を付与する付与部と、を備える。【選択図】図４ |
