High-resolution maps at 2695 MHz using the NRAO three-element interferometer have been obtalned for the linearly polarized and total radiation of 3C20. The synthesized beam width for the maps is about 6 in diameter. The total radiation shows a common structure composed of two unresolved components with larger-scale radiation between them. The polarized distribution shows good correspondence with the total distribution. The intense components are only slightly polarized whereas the central regions have polarizations as large as 20 percent.
