Abstract: We consider the degree of irrationality of some algebraic surface . Firstly we give an estimate of for a surface with a structure of a fiber space. Secondly we prove the existence of a nonsingular curve of genus 3 on for a certain elliptic curve with complex multiplications. As a corollary, we obtain that .
