In order to provide a tilt hinge small in size and diameter capable of generating a stable friction torque of approximately 100 kgf/mm, a hinge friction-rotatably coupling a first member and a second member that are relatively opened/closed includes: a holder attached to one of the first member and the second member; a shaft attached to the other one of the first member and the second member to be rotatable relative to the holder and immovable in an axial direction; a plurality of first friction discs restrained by the holder to be rotatable and movable in the axial direction, with the shaft being inserted through insertion holes thereof; a plurality of second friction discs interposed between the first friction discs to be movable in the axial direction with rotation thereof restrained by the shaft; and a plurality of disc springs and/or spring washers attached to the shaft so as to bring the first friction discs and the second friction discs to be in contact with each other by pressing the first friction discs and the second friction discs in the axial direction, wherein the disc springs and/or the spring washers are provided outside the holder in which the first friction discs and the second friction discs are stacked on each other and inside the holder.
