The invention discloses a preparation method of a ferroelectric single crystal composite sheet and the composite sheet, and relates to the technical field of piezoelectric materials, and the preparation method comprises the following steps: cutting a ferroelectric single crystal into first crystal blocks; putting the first crystal block into a first solution for cleaning; the first crystal blocks are put into a mold, the mold is a cylindrical body with an opening in the top, a containing space is formed in the mold, and the first crystal blocks are arranged at intervals and put into the containing space of the mold; injecting an adhesive into the accommodating space of the mold so as to solidify and combine the first crystal blocks together to form a second composite crystal block; after the second composite crystal block is solidified, the second composite crystal block is separated from the mold; and cutting the second composite crystal block to obtain the ferroelectric single crystal composite sheet.
