A back cover with an antenna element includes a cover body having a main portion, and an antenna element. A periphery of the main portion protrudes frontward to form a peripheral wall. The cover body is further equipped with a magnetic part. The antenna element is assembled in the cover body. The antenna element has a base portion, a connecting portion, a first extension portion and a second extension portion extended upward from the base portion. The first extension portion is disposed adjacent to one side of the peripheral wall of the cover body. The second extension portion is adjacent to the first extension portion. A length of the first extension portion is longer than a length of the second extension portion. A connecting portion is connected between the first extension portion and a top end of the second extension portion.
