TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Components: The conductive material contains at least one of carbon black, graphite, carbon nanotube, carbon fiber, gold and silver.    TECHNOLOGY FOCUS - POLYMERS - Preferred Composition: The composition (C1) further comprises a conductive material. In the composition (C1), the ratio of the compound (I) is 0.01-10 parts by weight, when the compound, thermosetting polymer and conductive material are 100 parts by weight in total. Preferred Components: The thermosetting polymer contains at least one of phenolic resin, epoxy resin and polyester resin. SPECIFIC COMPOUNDS - 4 Compounds are disclosed as (I) i.e. 1H-tetrazole, 5-amino-1H-tetrazole, 5-methyl-1H-tetrazole or 5-phenyl-1H-tetrazole (IA).    EXAMPLE - A polyester resin was prepared as follows: dimethyl terephthalic acid (75 parts by weight (pbw)), dimethyl isophthalic acid (40 pbw), ethylene glycol (80 pbw), neopentyl glycol (60 pbw), and tetrabutyl titanate (0.1 pbw) were put in a flask, and ester exchange reaction was performed at 180 degrees C for 3 hours. Then, trimellitic anhydride (2 pbw) and sebacic acid (80 pbw) were added, and dehydration reaction was performed for one hour. Next, the pressure was reduced to less than or equal to 1 mm Hg, and polymerizing reaction was performed at 270 degrees C for 2 hours, so that polyester resin was obtained. The polyester resin (40 pbw) and diethylene glycol monoethyl ether acetate (100 pbw) were subsequently put in a flask, and dissolved at 80 degrees C. After cooling to room temperature, DURANATE (RTM: a block of hexamethylene diisocyanate) (5 pbw) was added, so that a binder resin (a resin material) was obtained. EC-DJ600 (RTM: Ketjenblack as conductive carbon black) (10 pbw), graphite (45 pbw) and binder resin (45 pbw) were mixed and dispersed in a three roll kneader, so that a solution containing the resin material and the conductive material was obtained. 1H-Tetrazole (0.3 pbw) was added to the solution to give a paste composition.
