A dielectric block provided in a dielectric antenna is formed with an organic polymer material containing a liquid crystal polymer and polytetrafluoroethylene. The added amount of polytetrafluoroethylene is 2 to 15% by volume based on the volume of the dielectric block. Preferably, the liquid crystal polymer has a flow beginning temperature of no lower than 310° C. and no higher than 335° C. The dielectric block may further contain a dielectric inorganic filler and in this case, the added amount of dielectric inorganic filler is 45% by volume or less based on the volume of the dielectric block.
