A connector has a plurality of terminals aligned in a left/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 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/right direction of the terminals, protruding toward an upper side from a lower side, and that catch in notches or holes formed in the left and right sides of the 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/right direction than the two locking convex portions, and that biases the cable inserted in the space toward a lower side of the space.
