A butterfly valve having an elastic contact sheet is provided to reduce the deformation and abrasion of the sheet to extend the durability and replacement time of components. A butterfly valve having an elastic contact sheet includes a valve body(1), a body sheet(2), a fixing ring(R), a valve disk(3), and a disk sheet(4). The valve body is provided with a movement path(11) and the body sheet. The valve sheet is mounted at the valve disk. The valve disk is installed in the center of the movement path of the valve body to be openable and closeable. A coupling protrusion(21) is formed at a rim of an outer coupling surface of the body sheet. The body sheet includes a first slope surface(22), a second slope surface(22'), and a pressed suspending groove(23). An elastic guidance hole(41) is formed at an upper portion of an inner center of the disk sheet. The fixing ring is installed in a coupling groove(12) of the valve body.
