PROBLEM TO BE SOLVED: To provide a printed antenna which can easily fine adjust the resonance frequency. SOLUTION: In a printed antenna, an antenna conductive pattern, comprising a power supply line extended in the upward direction, starting from below a substrate and an antenna element part extended in the upward direction from an upper end of the power supply line is formed on one surface of a dielectric substrate, and a reverse surface grounding conductive pattern is formed in a region below a line extended substantially horizontally from a position, corresponding to the upper end of the power supply line on the other surface of the substrate. A notch or a small piece of a pattern is added at the upper end of the reverse surface earth conductive pattern at a position which does not face the antenna conductive pattern.
