Abstract
Striped sheets each having a structure in which two types of first layers and second layers are stacked in the X direction are prepared. More specifically, first raw material sheets having the same composition as the first layers and second raw material sheets having the same composition as the second layers are regularly alternately stacked in the X direction to prepare a uniaxial stack. The uniaxial stack is then cut along the X direction to prepare the striped sheets. A large number of striped sheets and a large number of homogeneous sheets are then collected to form a sheet group. The striped sheets and the homogeneous sheets are alternately stacked in the Y direction different from the X direction to prepare a biaxial stack having two stacking axes in the X direction and the Y direction. The biaxial stack is fired to produce a ceramic structure.
