A slide ring seal, a slide ring seal apparatus, and a manufacturing method thereof are provided to reduce danger of assembling errors by improving the conventional slide ring seal and slide ring seal apparatus. A slide ring seal includes slide and corresponding rings(1,2). A sealed shaft(0) is connected with the corresponding ring as one body. The sealed shaft and the corresponding ring are made of the same material and formed a unit(11). The sealed shaft and the corresponding ring are made of hardened steel. The unit is formed by a cutting work. In case of manufacturing the unit by the cutting work, a lathe work is performed at low speed to form a first sealed surface(12) of the corresponding ring with roughness of 0.1~0.3. The slide ring has a second sealed surface(13). The first sealed surface of the corresponding ring is axially bent to be in contact with the second sealed surface.
