Connector and circuit-board-mounting case having connector

A connector comprising:

• a metal terminal defining a longitudinal direction, formed of sheet metal and connected to an end portion of a lead wire, the metal terminal being press-fit, in a press-fit direction, into a press-fit hole formed in a connector housing made of resin by pushing a counterpart connection portion of the metal terminal located on a rear end side of the metal terminal with respect to the press-fit direction, the metal terminal comprising a lead-wire connection portion located on a front end side of the metal terminal with respect to the press-fit direction;
• and
• a sealing elastic member, which is externally attached to an end portion of the lead wire located toward the metal terminal or to a portion of the lead wire located toward the end portion prior to press-fitting of the metal terminal into the press-fit hole, and which establishes a seal between an outer circumferential surface of the lead wire and a wall surface of the press-fit hole following the press-fitting of the metal terminal into the press-fit hole;
• the metal terminal further including a press-fit portion between the lead-wire connection portion and the counterpart connection portion, the press-fit portion comprising a curved portion of the sheet metal of the metal terminal, which curves around an imaginary axis extending in the longitudinal direction of the metal terminal;
• and
• the metal terminal being press-fit into the press-fit hole by virtue of the press-fit portion being press-fit into the press-fit hole.
