<p>In a wireless device provided with an antenna, which is separate from the antenna for which one casing is provided, at a joined part where two casings are joined, deterioration of the characteristics of the antenna provided at said joined part is reduced. The wireless device (1) has an upper casing (10) that incorporates a casing antenna (11) that resonates at a first frequency, a lower casing (20) that incorporates a matching circuit (23) for the casing antenna (11), a hinge unit (31) that joins the upper casing (10) and the lower casing (20) and incorporates a built-in antenna (32) that resonates at a second frequency that differs from the aforementioned first frequency and power feed units (33, 34) that join the matching circuit (23) to the casing antenna (11), and transmitting elements (12, 22) that transmit signals of the aforementioned first frequency and block signals of the aforementioned second frequency on at least the signal path connecting the casing antenna (11) and the power feed unit (33), or the signal path connecting the matching circuit (23) and the power feed unit (34).</p> |
