Cleaning agent for electroconductive paste and method for cleaning electroconductive paste

Abstract

Provided is an alkaline cleaning agent that does not tend to affect screen plates, and permitting easy removal of electroconductive paste adhered to the screen plate. One embodiment relates to a cleaning agent composition for electroconductive paste, the cleaning agent composition containing a compound (component (A)) represented by formula (1) and an aliphatic alcohol (component (B)) having 2-6 (inclusive) carbon atoms and a molecular weight of 40-120 (inclusive). The pH of the cleaning agent composition is 11.0 or more and less than 14.0. Relative to the total mass of the cleaning agent composition, the content of the component (A) is 0.1-5 mass % (inclusive) and the content of the component (B) is 5-40 mass % (inclusive). R1—O—(C2H4O)a-H  Formula (1) (In formula (1), R1 represents a C6-18 branched alkyl group and a, which is the average number of added mol of C2H4O groups, is a number 2-10 (inclusive).).
