Board waterproofing connector

A board waterproofing connector comprising:

• a circuit board having a flexible plane conductor;
• a metal terminal contacting the plane conductor;
• a fitting cover having a fitting portion into which a mating connector is adapted to be fitted, and having a holding portion that holds the metal terminal inside the fitting cover;
• and
• a seal member that demonstrates a sealing property and that is sandwiched between the circuit board and the fitting cover, wherein:
• the fitting cover has a lock portion attached to the circuit board;
• the circuit board has a locked portion onto which the lock portion is locked;
• the metal terminal has a held portion held by the holding portion, and a contact portion having a spring property and contacting the plane conductor;
• and
• in a state wherein the held portion of the metal terminal is held by the holding portion of the fitting cover and the seal member is sandwiched between the circuit board and the fitting cover, the lock portion of the fitting cover is locked onto the locked portion of the circuit board such that the seal member waterproofs a space between the circuit board and the fitting cover while maintaining contact between the contact portion of the metal terminal and the plane conductor through the spring property of the contact portion.
