This connector (1) is equipped with: a hard outer housing (31) integrally formed from a hard material and provided with a wire insertion cylinder section (32) into which a terminal fitting (21) and the end (12) of an electrical wire (11) are inserted; and a soft inner housing (41) integrally formed from a soft material within the wire insertion cylinder section (32) along with the terminal fitting (21) and the end (12) of the electrical wire (11). Soft inner housing-penetrating sections (37) are formed in the wire insertion cylinder section (32). An externally exposed section (43) externally exposed from the soft inner housing-penetrating sections (37) is formed in the soft inner housing (41). The external exposed section (43) serves as a sealing lip section for forming a seal with a mating connector.
