The present invention discloses a heating air mat comprising: a mat part which comprises an upper sheet and a lower sheet formed of a flexible material and disposed in a stacked shape, and a lateral sheet surrounding the lateral surfaces of the upper sheet and the lower sheet and having a sealed space formed therein, the mat part selectively expanding as air is injected in the sealed space; a gap-maintaining part of which at least one or more are formed and are provided inside the sealed space, and which is connected to each of the upper sheet and the lower sheet between the upper sheet and the lower sheet, and provides support so that when the mat part expands, the upper sheet and the lower sheet are leveled while having an even spacing distance therebetween; and a heating part which is formed of a flexible material, has at least one part thereof connecting to the gap-maintaining part and generating heat inside the mat part, and is disposed so as to be spaced apart from the lower sheet in the upward direction inside the sealed space when the mat part expands. |
