A branch connector capable of maintaining a sealing state for cables with different specifications is provided. A branch connector (10) configured to electrically connect cables together by cutting insulating sheaths in press-contact grooves includes a pair of first split housing (16) and a second split housing (30) that are coupled together via a connecting portion and can open and close, first holding portions (29) that are provided to the first split housing (16) and configured to hold the cables, and second holding portions (40) that are provided to the second split housing (30) and configured to hold the cables. In a state in which the first split housing (16) and the second split housing (30) are fitted together, the first holding portions (29) and the second holding portions (40) are in different locations from each other with respect to an extending direction of the cables and a direction perpendicular to the extending direction.
