The invention relates to an undergarment with the electric heating function made of far-infrared bluish dogbane fabric. The undergarment with the electric heating function made of the far-infrared bluish dogbane fabric comprises an undergarment body (1), wherein the undergarment body (1) is of a double-layer structure, an interlayer (2) is arranged in the garment body (1), heating pieces (3) are fixed in the interlayer (2), and the heating pieces (3) are connected with a storage battery (4) in the interlayer (2). The undergarment body is made of the fabric, wherein the fabric is formed by tightly combining a far-infrared coating, a bluish dogbane layer and a pure cotton fabric layer in sequence from inside to outside, the thickness of the bluish dogbane layer is 0.25 mm, the far-infrared coating is a foam coating, and the thickness of the far-infrared coating is 4 mm. According to the undergarment with the electric heating function made of the far-infrared bluish dogbane fabric, a human body can be heated, and thus the warming function is achieved. The fabric of the undergarment formed by stacking the far-infrared coating and the bluish dogbane layer, has multiple functions and has the advantages of being capable of promoting the blood circulation of the human body, regulating metabolism and reducing blood pressure of the human body and high in breathability.
