A surface mount antenna includes a substrate and a radiation electrode (having a predetermined resonance frequency) disposed on the substrate. An electrode is formed to cover four continuously connected surfaces including the front surface, the front end surface, the rear surface and the rear end surface of each substrate. Then, a dicer is used to cut a slit on the radiation electrode formed on the surface of the dielectric substrate. Here, the slit is arranged in a direction intersecting a direction alpha connecting the two end surfaces. Subsequently, the dielectric substrate is cut into a plurality of portions along the direction alpha, thus producing a plurality of surface mount antennas each including a substantially rectangular substrate and a radiation electrode formed essentially surrounding an outer circumference of the substrate. In this way, it is possible to produce a plurality of surface mount antennas in only one operation. Since each radiation electrode has a very simple shape, and since a dicer can be used to perform a high precision processing, it is easy to form each radiation electrode having a desired resonance frequency, by using a dicer to perform a cutting treatment to process the slit.
