We present new observations of IRAS 04000+5052, a Galactic H II region that is associated with a young stellar cluster and is possibly located in the Perseus arm. We have found that contrary to previous claims, this object is not a compact metal-poor H II region. The electron density and chemical composition of the nebula are similar to those of normal H II regions of the Galactic disk. The radial velocity of the ionized gas coincides with that obtained from CO observations, indicating that the nebula is associated with a molecular cloud. Probably, the ionizing source of the H II region is a Herbig Be star of spectral type B0.5. Based on observations made with telescopes operated on the island of La Palma by the Isaac Newton Group of Telescopes and Nordic Optical Telescope at the Spanish observatory of Roque de Los Muchachos of the Instituto de Astrofísica de Canarias.
