Provided is a sliding bearing having a center plate which is disposed between an upper case and a lower case and which includes a thrust sliding surface having excellent sliding properties and elastic force and a radial sliding surface having excellent sliding properties and rigidity. A sliding bearing 1 is provided with a center plate 4 disposed between an upper case 2 and a lower case 3. The center plate 4 is provided with: a plate body 10 which includes an annular thrust body portion 11 forming a thrust portion and a radial portion 12 having an inner circumferential surface 15 slidable relative to an inner circumferential portion 2C of the upper case 2; and a thrust plate 20 which forms the thrust portion, which is provided on the thrust body portion 11, and which has the thrust sliding surface 24 slidable relative to an upper base 2B. The thrust plate 20 having the upper surface 24 is formed from a thermoplastic elastomer. The thermoplastic elastomer has higher elasticity than thermoplastic resin forming the inner circumferential surface 15 of the radial portion 12.
