A sealing device comprises a sealing member (20) brought into contact with a contact surface (23) so as to be slidable in a predetermined sliding direction (X). The sealing member (20) comprises a sliding contact portion (42) containing a high polymer material to be brought into sliding contact with the contact surface (23). A plurality of recessed or protruding streaks (50), which are independent of one another, are provided side by side so as to constitute a column on a surface (47) of the sliding contact portion (42). |
