<P>PROBLEM TO BE SOLVED: To provide an IC card excellent in communication characteristic by connecting antenna ends in a card base with antenna connecting terminals of an IC module with a conductive paste containing a chelating agent or anticorrosive for reduced initial connection resistance. <P>SOLUTION: The contact-noncontact IC card has a structure in which two antenna connecting terminals 7a, 7b of an IC module are connected respectively to a leading end 21 and a trailing end 22 of an antenna in a card base 10 via a conductive paste inside an IC module mounting recess part 30. The antenna is formed using metallic foil or metallic wire. The leading end 21 and the trailing end 22 of the antenna are connected respectively to the two antenna connecting terminals 7a, 7b of the IC module 5 with the conductive paste containing a chelating agent or anticorrosive. <P>COPYRIGHT: (C)2009,JPO&INPIT |
