To provide a ridge-end decorative tile capable of penetration of rainwater by preventing weathering of an adhesive member such as mortar cement formed and fixed between a reverse surface part of the ridge-end tile and a tail end part of a ridge tile.

A protective plate (b) having a plane part 8 having a collar- shaped projection 7 extending in the outside direction along the rear end of a peripheral edge part 3 being a side surface and an upper surface when arranging a ridge-end tile and expanding as a vertical plane capable of forming a cutout part adjusted to a cross section vertical to the lengthwise direction of the ridge in the rear of the ridge-end tile and an umbrella part 11 extending forward along the side edge and the upper edge of the plane part 8, is arranged so that the plane part 8 for forming the cutout part strides over the ridge, and the protective plate is engaged with and fixed to the ridge-end tile so that the umbrella part 11 covers the projection 7 arranged on the ridge-end tile to be thereby solved by forming a ridge-end tile (a) having a ridge tail end part surrounded by a reverse part 4 and the protective plate (b) of the ridge-end tile.
