PURPOSE: To reduce the variation in conductivity of resin compsn. contg. an electron-conductive substance due to its variations in voltage and temp. by compounding the compsn. with an ion-conductive substance.

CONSTITUTION: This conductive resin compsn. is obtd. by compounding a resin with 3-40wt.% at least one electron-conductive substance selected from the group consisting of a conductive carbon black, a conductive carbon fiber, a conductive carbon whisker, a conductive metal oxide, and a conductive alkali metal titanate. The compsn. is then compounded with a 0.5-20 wt.% soln. of an ion-conductive substance selected from the group consisting of org. electrolytes (e.g. a quaternary ammonium salt) and inorg. electrolytes contg. at least one kind of cation selected from the group consisting of H+, Li+, Na+, K+, Cs+, Ag+, Cu2+, and Zn2+ in such an amt. of the soln. that the amt. of the ion-conductive substance is 0.05-10wt.% of the compsn.
