PURPOSE: A rechargeable electric heating mat is provided to prevent the risk of fire and the harmfulness due to an electromagnetic wave according to the use of an alternate current by using a DC current which is provided from a rechargeable electric battery as power. CONSTITUTION: A mat main body(12) can be fold to a multi-stage. An auxiliary mat(14) is detachably combined in the side edge of the mat main body. The mat main body and the auxiliary mat are arranged to enable a heating line(16) to be fold inside a heat insulator when a current is applied. An outer cover is covered outside the heat insulator(18). The length of the mat main body is relatively longer than that of the auxiliary mat. The mat main body forms a plurality of folding parts(22) with a predetermined interval in order to be fold to a multi-stage along a longitudinal direction. |
