PROBLEM TO BE SOLVED: To provide a tarpaulin with superb stable antistatic properties which is free from the run-off of an antistatic agent by the plural number of times of cleaning by constituting tarpaulin of a polymer containing a specified ratio of structure units expressed by a specific formula and a polyolefin modified product, applied to at least, one face of a base cloth of a synthetic fiber woven fabric. SOLUTION: A copolymer containing structural units expressed by general formulae I to III in the ratio of 10-50 mol.% of ethylene structural unit of formula I, 40-60 mol.% acrylate structural unit of formula II and 15-40 mol.% polyoxyalkylene allyl ether of formula III and a polyolefin modified product obtained by modifying polyolefin by carboxylic acid or a carboxylic acid anhydride are applied to at least, one face of a base cloth of a synthetic fiber woven fabric. In the formulae I-III, R1 is a 10-50C straight-chain or branched chain alkyl group; R2, R3 are independently a 1-10C alkyl group; R4 is a 2-10C straight- chain or branched chain alkylene group; and n is an average numerical value of 2-20.
