PROBLEM TO BE SOLVED: To prevent the deterioration, drying and consumption of a high viscous fluid caused by use and sticking of dust to the high viscous fluid, by restraining a squeak of a disc brake by damping performance of the high viscous fluid (a lubricant). SOLUTION: An outer shim 60 is interposed between a back board 41 of an outer pad 40 and a reaction part 33 of a caliper 30. The outer shim 60 has a first plate 61 arranged on the back board 41 side, a second plate 62 arranged on the reaction part side and a third plate 63 arranged between the first plate 61 and the second plate 62 and forming a through-hole 63 in a part pressed by the reaction part 33. The third plate 63 is respectively adhered to the first plate 61 and the second plate 62, and squeak preventive grease 67 is fluidly sealed in a storage chamber R1 partitioned by a through-hole 63a of the first plate 61, the second plate 62 and the third plate 63.
