<P>PROBLEM TO BE SOLVED: To provide an electronic circuit unit which has a waterproof function preventing water from intruding into a coupling portion between a circuit board and a connector for external connection. <P>SOLUTION: An electronic circuit unit comprises: a circuit board 10 having first and second edge parts 12A, 12B provided with multiple connection conductors 14A; a case 20 housing the circuit board 10; first and second connector which have first and second terminals 30A, 30B respectively attached to terminals of multiple electric wires W and first and second housings 40A, 40B respectively holding the first and second terminals 30A, 30B; electric wire side sealing members 50 provided at the respective electric wires; and first and second connector side sealing members 60. The case has a first opening and a second opening, and the circuit board is inserted into the case from one of the openings to be housed therein. The connector side sealing member is disposed between the housing and the case so as to seal the interior of the case. Each electric wire side sealing member is disposed between the electric wire W and an inner peripheral surface of a terminal insertion part 45 so as to seal the interior of the case. <P>COPYRIGHT: (C)2013,JPO&INPIT |
