There is provided a press-fit connector 20 in which connecting faces 21a and 22a of a cover 21 and a 22 are moved in a direction in which both the connecting faces approach each other and moved to connecting position, the connector housing 22 is provided with a plurality of partition walls 24 for partitioning the housing into terminal accommodating chambers 23, the cover 21 is also provided with a plurality of partition walls at positions opposed to the former partitioning walls, both the partitioning walls 24 move in a direction in which they approach each other when the connecting faces moved to the connecting position, and tip end faces of both the partitioning walls 24 roughly abut against each other at the connecting position. When the connecting faces move to the connecting position, the positioning operation is started before the press-fit terminals and the partitioning walls of the cover 21 which are opposed to the press-fit terminals come to the position where they can come into contact with each other, and if a direction in which the partitioning walls 24 extend is defined as an extending direction, positioning projections 32a and positioning recesses 32b for positioning the cover 21 and the connector housing 22 in a direction S perpendicular to the extending direction T.
