PROBLEM TO BE SOLVED: To provide a lens antenna in which focal length is adjusted substantially constantly regardless of variation in dielectric constant, and excellent antenna gain is ensured while suppressing individual variation. SOLUTION: The lens antenna 10 employs a composite dielectric lens 11 obtained by molding a composite dielectric material containing a dielectric inorganic filler and an organic polymer material, wherein the composite dielectric lens 11 has dielectric constant anisotropy. Focal length adjusting mechanisms 11d, 12b and 15 fix the composite dielectric lens 11 to the antenna body 12 such that the angle can be adjusted about the axis O thereof.
