<p><P>PROBLEM TO BE SOLVED: To provide a portable information processing device capable of maintaining proper antenna characteristics, while reducing the size of an antenna substrate by neglecting a space to be required for fixing a screw, without fastening and fixing by the screw etc. <P>SOLUTION: Ground patterns 1a are wired at both sides of the antenna substrate 1, and an antenna pattern 1b is formed at a portion sandwiched between the ground patterns 1a, which is formed by a metal thin-film layer for establishing transmission and reception of radio waves. A coaxial cable 4 is fixed on the antenna substrate 1. When the antenna substrate 1 is to be mounted to a notch 2a in a side surface of a portable information processing device body, height of the coaxial cable 4 is to correspond to the height of a fitting portion 3c of an upper case 3 and a fitting portion 2c of a lower case 2; while the fitting portions 2c, 3c are made to contact so as to press a shielded wire rod 4b, when the upper case 3 and the lower case 2 are to be fixed by fitting. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
