From NANTEN 12CO Galactic Plane Survey, we have discovered a group of linearly aligned molecular clouds, a possible candidate for molecular gas formed through the interaction of a relativistic jet with the interstellar matter. Physical properties of the molecular clouds such as line width, size, and mass are not different from those of typical molecular clouds in the galactic plane. This jet-like feature is highly elongated perpendicular to the galactic plane by ~500pc with a width of 10pc towards l ~ 348.5 degrees at a kinematic distance of ~6kpc, where at least a few energetic objects are located in the galactic plane. We suggest a relativistic jet driven by a compact source possibly a black hole created the present features. A proposal is submitted to observe these molecular clouds by Mopra telescope. The observation aims to reveal detailed structures of the molecular clouds and to study the interaction between an interstellar medium and the relativistic jets. Since black holes have found only ~20 by non-thermal radio and X-ray, through the observations we consolidate a way to search black holes in the Milky Way and will search much more compact stars as probed molecular clouds.
