Also, for example, in this connector 1, it is possible to narrow the waterproof area covered by each of the gaskets 65 and 66. With these effects, the connector 1 of this embodiment has improved waterproof performance, and it is possible to improve product quality.

[0042] In the connector 1 of this embodiment, the first opening 50a 1 and the second opening 50b 1 Since each of the openings has a small opening area in a different location, the wiring path and positioning of the electric wires (first electric wire 21, second electric wire 22, third electric wire 23, fourth electric wire 24, fifth electric wire 25, sixth electric wire 26) can be precisely regulated, and pinching of the electric wires can be prevented when assembling the first cover 61 and the second cover 62.

[0043] In addition, in the connector 1 of this embodiment, the first cover 61 and the second cover 62 are formed into a flat plate shape to reduce the convex shape, thereby making it possible to reduce the size of the connector 1. Therefore, the connector 1 of this embodiment also makes it possible to reduce the size of its own accommodation space in the mating device. [Explanation of symbols]
