The present invention is to provide a pre-treatment agent for a vulcanized rubber, the pre-treatment agent being a treatment agent for treating a surface of a vulcanized rubber before application of an adhesive to the vulcanized rubber, and allowing the adhesive to exhibit excellent adhesiveness after curing. The pre-treatment agent for a vulcanized rubber according to an embodiment of the present invention is a pre-adhesion treatment agent for a vulcanized rubber, the treatment agent containing: a non-ionic surfactant, water, and an organic solvent; the non-ionic surfactant having an HLB value of 4.5 or greater and 10.5 or less and being a compound represented by Formula (1); the organic solvent being a compound represented by Formula (2); and a content of the non-ionic surfactant being from 0.5 to 30 mass%. HO-(R11-O)n-R12 (1) R11 represents -CH2-CH2-, -CH(CH3)-CH2-, or -CH2-CH(CH3)-. R12 represents an aliphatic hydrocarbon group. n represents an integer of 1 or greater. R21R22N-CO-R23 (2)R21, R22, and R23 each represent a hydrogen atom or a substituent. R21 or R22 may be bonded to R23 to form a ring.
