A molecular cloud has been discovered from a large-scale (C-13)0 (J = 1-0) survey in the Cep OB4 region. Detailed properties of this cloud, named as M120.1 + 3.0, are investigated on the basis of molecular-line observations and the IRAS data. The cloud, appearing dense and filamentary, is composed of two parts. Each of the two parts has a size of 6 x 1 pc and a mass of 800 solar mass, similar to dark clouds observed within 500 pc of the solar neighborhood. The cloud is associated with about 12 low-luminosity IRAS sources, and the locations of the sources show remarkable coincidence with the distribution of the dense molecular gas. Two molecular outflows have been discovered toward two of IRAS sources.
