A connector has a plurality of terminals aligned in a left to right direction, and a housing that configures a space in which a flat cable can be inserted from a front side to a rear side and holds the plurality of terminals on an inside of the space. The housing has two locking convex portions positioned on the inside of the space and in the left to right direction of the plurality of terminals, protruding toward an upper side from a lower side, and that catch in notches or holes formed in the left side and the right side of the flat cable. Finally, the housing has a biasing member that is positioned on the inside of the space, formed on an upper side of the space, arranged closer to a center in the left to right direction than the two locking convex portions, and that biases the flat cable inserted in the space toward a lower side of the space.
