PROBLEM TO BE SOLVED: To develop a miniatured antenna which can suppress variations in an antenna frequency characteristic caused by injection-molding. SOLUTION: In the miniaturized antenna, the dielectric material of a conductor pattern including an antenna element is injection-molded to fix the pattern, and is made in the form of a chip. The metal material of the conductor pattern satisfies a relation of a Z value found by an equation of Z=(tensile strength (N/mm<SP>2</SP>))×(softening temperature (°C))/100 not smaller than 2,000 (N/mm<SP>2</SP>×°C).
