Abstract: A loop antenna device includes a loop antenna having a high noise resistance performance. In a loop antenna having a shield member covering a looped conductor portion formed in a loop shape from a conductive wire, a non-covered portion where the looped conductor portion is not covered is formed in correspondence with a portion of the conductive wire including a reference position for the symmetry of two terminals for connection between the antenna device and a reception circuit. This provides a balanced shield structure. Besides, a line for connecting one end of the conductive wire to the ground potential and a line for connecting the shield member to the ground potential are individually separate from each other, whereby reception of a voltage fall due to common impedance by the antenna is suppressed.
