PROBLEM TO BE SOLVED: To obtain a new lightweight oligomer excellent in mechanical characteristics, moldability and stability and useful for lithium battery, etc., by forming a specific chemical structure. SOLUTION: This oligomer has a structure of the formula [R1 is a 1-12C alkyl, a 1-12C alkoxyalkyl, a 6-7C aryl, an alkaryl, etc.; X is O, S, SO, SO2 , NH, etc.; (A)q is a polymerized unit of a monomer having a functional group forming a complex with an electroconductive metal salt; (B)r is a polymerized unit of a monomer not forming a complex with an electroconductive metal salt; Z is H or R1 -X; (q) is 1-25; (r) is 0-24; (q+r) is 1-25]. Furthermore, the oligomer is preferably blended with 5-20wt.% one or more electroconductive metal salts and the oligomer preferably contains (A) 5-50wt.% one or more terminal group units of the formula R1 -S, (B) 0-95wt.% polymerization unit of the formula CH2 =CH-COO-CH2 -CHR-R2 (R is H or methyl; R2 is H, a 1-20C alkyl, etc.) and (C) O-95wt.% polymerization unit of the formula CH2 =CR- COO-(CH2 CHR-0)n -R2 and polymerization degree of the (meth)acrylic acid ester monomer components is 1-25.
