A cable entrance module is provided at a position of equipment at which a cable enters the equipment from the outside. The cable is inserted through the inside of the cable entrance module. The cable entrance module includes an entrance-side membrane, an exit-side membrane, and a viscous-matter-filling portion. The inside of the filling portion is filled with viscous matter. The entrance-side membrane has such strength that when it is pierced by the extending end of the cable it is pushed by the extending end of the cable. The exit-side membrane has a strength such that it is not pierced by the viscous matter when the cable pierces the entrance-side membrane, enters the viscous-matter filling portion, and moves through the viscous matter in the viscous-matter filling portion while pushing the viscous matter aside. The exit-side membrane is pierced by the extending end of the cable when it is pushed by the extending end of the cable.
