PROBLEM TO BE SOLVED: To provide a pulp washing agent containing a surfactant having excellent functions of removing organic matters (soiling components) such as lignin decomposition products and resins deposited on a pulp as compared to conventional nonionic surfactants. SOLUTION: The pulp washing agent includes a nonionic surfactant (X) represented by the general formula (1): R 1O[(C2H4O)p/(C3H6O)q]H (1) [in the general formula (1)， R1 represents a branched alkyl group of a carbon number of 8-9; p is a number average addition mole number of an ethyleneoxy group and is a number of 1-5; q is a number average addition mole number of a propyleneoxy group and is a number of 1-10; [(C2H4O)p/(C3H6O)q] represents that the addition style of the ethyleneoxy group and the propyleneoxy group is a random form or a block form. Preferably， the addition form of the ethyleneoxy group and the propyleneoxy group is block].SELECTED DRAWING: None
