On a surface of a transfer sheet, a resistor paste is first patterned, and a binder resin thereof is then heat-cured to form resistor layers. Next, an electrode paste containing a binder resin, which has a thermosetting temperature lower than a thermosetting temperature and a glass transition temperature of the binder resin of the resistor layers, is patterned on surfaces of the resistor layers and is then heat-cured, thereby forming electrode layers. By the steps described above, powdered silver contained in the electrode layers is unlikely to ooze into the resistor layers.

Resistor and method for producing the resistor

A resistor is provided that is made by laminating at least two resistive layers, where these resistors have conductive particles held in a binder resin. The resistors are laminated such that a top resistor covers a bottom resistor, and a surface of the top resistor is exposed. The resistivity of the top resistor is made smaller than that of the bottom resistor. The top resistor contains carbon fiber and carbon black, where the central particle size of the carbon fiber ranges from 3.5 to 9.0 &mgr;m. The resistor has excellent durability and micro-linearity characteristics. The resistor may also be used as a variable resistor.

A variable resistor uses a carbon fiber-base resistor with a specific distribution of carbon particle sizes. Because the particle size distribution of carbon fiber is approximately equal to the normal distribution and 80% by volume or more carbon fiber is included in the particle size range from 1 to 20 &mgr;m, high conductivity in the fiber length direction of carbon fiber that is served as structural material for improving the wear resistance does not affect the micro-linearity.

The present invention provides a curable resin compound which is soluble in organic solvents and easy to use, and a method for producing the same. The curable resin compound comprises a structure and crosslinkable groups which end-cap the structure, the structure comprising three or four non-substituted benzene rings each of which is joined with each adjacent benzene ring by an ether or ketone linkage so that both types of linkages are present in the structure. Though the curable resin compound exhibits satisfactory solubilities in organic solvents, a composition comprising the compound can be cured by a crosslinking reaction to be insoluble in the organic solvents while being provided with improved solvent resistance and chemical resistance. Accordingly, the present invention also provides a cured-resin material derived from the aforementioned curable resin compound, the cured-resin material being excellent in solvent resistance, chemical resistance and thermal resistance.
