A deck panel, according to the present invention, comprises: a steel sheet; a thermoplastic polyolefin (TPO) sheet provided in parallel with the steel sheet while maintaining a state in which the steel sheet is separated therefrom at a predetermined distance; and foam filled between the steel sheet and the TPO sheet, wherein the TPO sheet has an extended part extended outward further than the end of the foam. The deck panel having the TPO sheet, according to the present invention, has advantages of sealing a gap between two deck panels without a separate additional member when two deck panels are connected and ensuring the flatness of the TPO sheet at a reference value or higher even though a large amount of heat-insulating material and filler is injected between the steel sheet and the TPO sheet. |
