This connector has a case-side seal groove in which a case-side seal member is arranged.

According to the above aspect, the electrical connection portion between the terminal and the metal wire is embedded in the connector housing. Therefore, the connector housing prevents water from adhering to the connection portion between the terminal and the metal wire. Therefore, corrosion of dissimilar metals at the connection portion between the terminal and the electric wire can be suppressed.

(2) A shield shell that covers the outside of the connector housing is provided, the shield shell has an exposed port that communicates between the inside and outside of the shield shell, and the connecting portion projects from the exposed port to the outside of the shield shell. The connector housing has a shield-side seal groove in an outer wall surface of the connector housing, in which a shield-side seal member for sealing between the outer wall surface of the connector housing and the inner wall surface of the shield shell is disposed. , assuming that the direction in which the connecting portion projects from the connector housing is a first direction, the shield-side seal groove is defined as a portion of the outer wall surface of the connector housing from which the connecting portion projects when viewed from the first direction; It is preferable that the connector housing be provided between a part of the outer wall surface of the connector housing and a part from which the electric wire is drawn out.

According to the above aspect, the shield-side sealing member can prevent water that has entered the inside of the shield shell from the exposure port from reaching a location on the outer wall surface of the connector housing where the electric wire is pulled out. Therefore, it is possible to further suppress the water from adhering to the connecting portion between the terminal and the metal wire. As a result, dissimilar metal corrosion at the connection portion between the terminal and the electric wire can be further suppressed.

(3) If the protruding direction of the connecting portion from the connector housing is a first direction, the plurality of electric wires are pulled out from the connector housing along a second direction intersecting the first direction, and It is preferable that the positions where the plurality of electric wires are drawn out on the outer wall surface of the connector housing are arranged along a third direction that intersects the first direction and intersects the second direction.

Therefore, the connector housing can be further downsized. Further, by aligning the fourth direction with the third direction, it is not necessary to provide a large number of bent portions in the first terminal. Therefore, it is possible to suppress the shape of the first terminal from becoming complicated.

(9) Preferably, the connection portions of the plurality of terminals are arranged in a direction perpendicular to the third direction.
