摘要： Of margins of a resin molding with an antenna element buried therein which lie around the antenna element, a margin on that side of the resin molding where a gate mark remains is made larger than margins on other sides where there is no gate mark. Particularly, when the antenna element has a line antenna portion and a capacitance-adding portion provided at a distal end of the line antenna portion, the resin molding is injection-molded in such a way that a gate mark can be formed on that side where the capacitance-adding portion is located. Those portions of the resin molding where the terminal portions are led out are dented from levels of portions around those portions. This provides a chip antenna which has a simple structure with a high mechanical strength and does not prevent separation or cracking from occurring in the resin molding in which the antenna element is buried and a method of manufacturing the chip antenna.
