PROBLEM TO BE SOLVED: To provide a resin pellet mixture whose characteristics deteriorate scarcely, when molded, and which has excellent hydrolysis resistance and excellent dry thermal deterioration resistance, and is suitable for harness connector uses. SOLUTION: This resin pellet mixture for connectors, comprising (A) masterbatch pellets obtained by compounding, melting and kneading (A-1) polybuthylene terephthalate with functionality-imparting agents in high concentrations and (B) polybutylene terephthalate pellets in a (A)/(B) weight ratio of 2/98 to 50/50, is characterized in that the terminal COOH group concentration of (A-1) the polybutylene terephthalate of (A) the masterbatch pellets is <=30 eq/T.
