PROBLEM TO BE SOLVED: To relieve a concentration of return current in the vicinity of feeding point of antenna 1 in a wireless device equipped with a plurality of antennas without limiting the usage of casing materials, or adding parts. SOLUTION: The wireless device 1 comprises a first casing 11, a second casing 12, and a connection part 13, and is equipped with a first antenna 21 on an upper part of a substrate 15 built in the second casing 12, and a second antenna 23 on a lower part thereof. Both the feeding point 22 of the first antenna 21 and a ground point 24 of the second antenna 23 are provided near a long side 16 of the substrate 15. The return current of the first antenna 21 is distributed over a total electric length of the second antenna 23 from the feeding point 22 through the ground point 24. COPYRIGHT: (C)2007,JPO&INPIT
