The present invention provides a laminated quartz, in which a plurality of quartz are laminated. The laminated quartz comprises: a first quartz member including a plate-shaped first main body and a first protrusion portion formed by protruding to the outside of the rim of the first main body; a second quartz member including a plate-shaped second main body configured to be opposite to the first quartz member and a second projection portion formed by protruding to the outside of the rim of the second main body; and a plate-shaped intermediate quartz member configured between the first quartz member and the second quartz member. The first protrusion portion and the second protrusion portion are formed respectively on the corresponding positions of the first quartz member and the second quartz member in an opposite manner. Each of the first projection portion and the second projection portion is provided with a suction hole penetrating through the first projection portion and the second projection portion. The s
