A plane truss girder for a deck is provided to have structural stability and economical efficiency and to apply to an integral deck effectively by minimizing eccentricity at a contact point of an upper chord of a truss and a lattice and retaining two contact points, thereby securing contact strength. A plane truss girder for a deck is formed by stretching a foot part of a lattice(3) and welding to the side of a lower chord(2) alternately, and stretching a head part of the lattice and welding to the side of an upper chord(1), alternately.
