In a thermal line head according to a first aspect of the invention, a monolithic electrical conductive pattern is formed on a base plate. The monolithic pattern includes plural sets of two electrodes, with a constriction extending between the two electrodes in each set. A cross-sectional area of the constrictions is smaller than that of the electrodes, whereby each of the constrictions serves as an electric resistance element. In an ink transfer printer, a frame, with an opening, is fixed on the thermal head such that the elements are included in the opening. A film sheet covers the frame, such that the opening is defined as an ink space, and plural pores in the sheet are arranged along an alignment of the elements, with at least one pore being allocated to each of the elements. When each of the elements is electrically energized to generate thermal energy, an ink drop appears on the film sheet from a pore corresponding to the localized generation of the thermal energy.
