A disc brake shim plate including a metal plate and a rubber section formed on at least one side of the metal plate. The rubber section includes an elastomer and carbon nanofibers having an average diameter of 0.5 to 500 nm and dispersed in the elastomer; the rubber section in uncrosslinked form has a first spin-spin relaxation time (T2n), measured at 150° C. by a Hahn-echo method using a pulsed NMR technique with 1H as an observing nucleus, of 100 to 3000 microseconds, and a fraction (fnn) of components having a second spin-spin relaxation time (T2nn) of less than 0.2; and the elastomer is one material selected from a natural rubber, an ethylene-propylene rubber, and a nitrile rubber.
