PROBLEM TO BE SOLVED: To reduce noise at a radio system in a communication electronic device.SOLUTION: A communication electronic apparatus includes: a bottom cover 10; a loop antenna 1 for forming an electromagnetic field; a communication circuit connected with the loop antenna 1; a battery pack 4 which is a metal part; a magnetic sheet 3 which is placed between the loop antenna 1 and the battery pack 4 and comprises a pushing-out part pushing out to the outside than the periphery of the loop antenna 1; a wiring board 12 which is placed on the battery pack 4 and on which an IC 12a and the like are mounted; and a cover with a display 11 placed on the wiring board 12. The amount of pushing-out of the pushing-out part of the magnetic sheet 3 from the periphery of the loop antenna 1 as a reference point is equal to or more than two times the wiring width of the loop antenna 1.SELECTED DRAWING: Figure 15 |
