A waterproof connector has an inner housing, in which a plurality of terminal housing chambers are formed for the housing of individual terminals at the ends of wires, and an outer housing, into which the inner housing is fitted, in which wire
insertion holes are formed on a wall that opposes the terminal housing chambers, and further in which is formed rubber cover housing depressions that house a rubber
waterproofing cover that seals the inside of the terminal housing chambers, in positions that are opposite each wire
insertion hole on the inside of the wall. The rubber
waterproofing cover is formed by a plurality of individual rubber cover pieces that are held in intimate contact inside the rubber cover housing depressions, and a holding plate part with which the individual rubber
waterproofing cover pieces are integrally formed, which is held between the inner housing and the outer housing, and which makes a seal between the rubber cover housing depressions and the terminal housing chambers.
