A sealing apparatus is provided that is capable of inhibiting a degradation in electrical conductivity performance. The sealing apparatus includes an outer seal part and an inner seal part, and conductive grease housed in a space. An outer elastic body part of the outer seal part is formed from an elastic body having electrical conductivity and includes a dust lip, a conduction lip, and a gasket part. At an annular fitting surface, the inner seal part is attached to the outer seal part. An inner elastic body part of the inner seal part is formed from an elastic body having electrical conductivity and includes a grease lip. The outer seal part has a spring that is put on an outer periphery side of the conduction lip to press the conduction lip against an inner peripheral member.
