Patent ID: 8791870

Claim:
A portable electronic device, comprising: a first body including a first face; a second body including a second face; a connecting portion that connects the first body and the second body so as to be openable and closable around an opening-and-closing axis, and transformable into an opened state in which the first face and the second face are disposed to be separated from each other, and a closed state in which the first face and the second face are disposed to be superimposed in a state of being adjacent to each other; and a loop antenna that is disposed in the first body and the second body, and is transformed such that a loop is formed in the opened state and the loop is not formed in the closed state, wherein the connecting portion connects the first body and the second body such that the second body is rotatable with regard to the first body around a rotational axis that intersects the opening-and-closing axis, and wherein, in a case in which the second body is rotated around the rotational axis such that the second face is oriented to an opposite side, the loop antenna is transformed to be twisted such that the loop is not formed even in the opened state.
