Polybutylene terephthalate resin composition and molded article

A connector connection port, wherein:

• the connector connection port is formed of a molded body obtained by injection molding a polybutylene terephthalate resin material, and a boss part is provided in a protruding form on an outer peripheral surface or inner peripheral surface of the connector connection port,
• voids are present in the polybutylene terephthalate resin material in the boss part and a lower part of the outer peripheral surface or inner peripheral surface on which the boss part is provided,
• when a sum total of cross-sectional areas of voids which are present in a region lying at a height of 0 to 0.5 mm from the outer peripheral surface or inner peripheral surface in the boss part is denoted by S1, a sum total of cross-sectional areas of voids which are present in a region lying at a depth of 0 to 0.5 mm from the outer peripheral surface or inner peripheral surface on which the boss part is provided is denoted by S2, and a total area of S1 and S2 is 100%, an areal ratio of S1 is 5% to 45% and an areal ratio of S2 is 55% to 95%,
• the polybutylene terephthalate resin material is a polybutylene terephthalate resin composition having a crystallization temperature of from 175 to 193° C., and
• the polybutylene terephthalate resin material comprises 100 parts by mass of a polybutylene terephthalate resin and 5 to 30 parts by mass of an elastomer, and the elastomer is within a phase of the polybutylene terephthalate resin.
