PURPOSE: A method for manufacturing a heating pad and a heating pad thereof are provided to manufacture the heating pad of wide area by using a power saving high efficiency power consumption method which can give warmness to the human body as consuming less power. CONSTITUTION: A heating pad body (110) is constituted by embedding a number of divided heating elements (130a,130b,···,130n) into one surface material (160). A number of DC power supply units (150a,150b,···,150n) are connected to independent control units (170a,170b,···,170n) respectively. The control unit supplies a power source to a corresponding divided heating element connected with electric wires (140a,140b,···,140n). The number of circuits of the divided heating element is equal to the number of the DC power supply units. Resistance of each divided heating element is 2Ω~5Ω |
