<P>PROBLEM TO BE SOLVED: To control a frequency of a non-contact IC card to be within a desired frequency band without a frequency control step after portable terminal device assembly. <P>SOLUTION: The present invention is applied to a method for manufacturing a portable terminal device with a built-in non-contact IC card. The manufacturing method includes: a step of manufacturing an antenna of the non-contact IC card; a step of classifying the antenna on the basis of frequency characteristics; a step of mounting components other than the antenna on a substrate; a step of classifying the substrate on the basis of frequency characteristic when the components are mounted on the substrate; and a step of combining the antenna and the substrate on the basis of a group into which the antenna is classified and a group into which the substrate is classified and mounting the combined antenna and substrate in a housing to manufacture the portable terminal device. <P>COPYRIGHT: (C)2012,JPO&INPIT |
