Abstract: Electrically heated underpants are revealed. The electrically heated underpants include an underwear main body, at least one pocket arranged at an outer surface of a front side or a rear side of the underwear main body, and at least one piece of electrically heated textile mounted into the pocket. The pocket is corresponding to abdomen or a lower back of users. The electrically heated textile generates heat and maintains a constant temperature after a current passed therethrough. Thereby the electrically heated underpants can keep users' abdomen and waist warm and further provide health benefits such as keeping the body warm, relieving dull pain in abdomen during the menstrual period, reducing waist and abdominal pain, etc.
