PROBLEM TO BE SOLVED: To make an antenna coil to receiver power transmission, etc., easily manufacturable by radiowave between the antenna coil and an antenna coil provided in a reader/writer, with a low resistance so that the power loss is lowered. SOLUTION: This IC card is constituted by forming the antenna coil on a substrate 4 and mounting an IC chip connected with the antenna coil. In this case, the wiring 5 of the antenna coil, etc., is formed by fusing particles of solder with a low melting point in conductive paste formed by mixing and dispersing conductive particles 12 with a high melting point and the particles of solder with a low melting point in resin and performing metal coupling of the particles of solder with a low melting point with the conductive particles 12 with a high melting point.
