Provided are a slide bearing and a manufacturing method of the same, which allow for reduction in the number of component parts and for resultant reduction in costs.
The slide bearing (1) is made of synthetic resin and has the upper case (2), the lower case (3) combined with the upper case (2), and the annular center plate (4) placed between the upper case (2) and the lower case (3) so as to allow relative rotation between the upper case (2) and the lower case (3). The center plate (4) is integrally formed with the lower case (3). The joining surface (34) of the lower case (3) to the center plate (4) has the grip part (35), and the joining surface (41) of the center plate (4) has a grasp on the grip part (35).
