Disclosed is a thin-film resistor element for an ink jet head. In the thin-film resister element, a protective film is used having a multi-layered structure, the proportion of Ar atoms contained in a lower area of the protective film located in contact with the heating resistor is set between 0.2 wt % and 6.0 wt %, and that in an upper area of the protective film is set between 1.0 wt % and 9.0 wt %.

A probe for reading an information from an object and/or inputting an information to an object is disclosed. The probe has a supporting member and a rod-shaped projection of which the end is positioned opposed to the object for information reading therefrom and/or information input thereto. The rod-shaped projection protrudes from a partial area of the supporting member. The information reading from the object and/or information input to the object is effected at the longitudinal end of the probe. The probe provides precise and accurate output and/or input of information regardless of the surface state of the object.
