PROBLEM TO BE SOLVED: To provide a chip antenna for terrestrial DMB (Digital Multimedia Broadcasting). SOLUTION: The chip antenna is characterized to include a main antenna element (200) in which two or more unit lamination structures (LYn) of a conductivity pattern with a meander line structure to a Z-axis direction of a XZ plane, are arranged to a Y axis direction in a dielectric block (100) in which two or more dielectric layers with a XY plane are laminated to the Z-axis direction, laminated structures (An) connected by the meander line structure to the Y-axis direction with the respective adjoining unit lamination structures, are formed, two or more above-mentioned lamination structures (An) are arranged to a X-axis direction, and connected with the respective adjoining lamination structures by the meander structure in the X-axis direction; and an auxiliary antenna (300) which is formed in an upper side or a lower side of the dielectric layer of the main antenna element (200) in a T character shape, connected with an end part of the main antenna element (200) through a conductive via hole, breaks up current distribution of the main antenna element (200), and expands the bandwidth.
