We study the structure of the function field K of the quintic Fermat curve F(5) in the following way: Let K-m be a g-maximal rational subfield of K. Then the field extension K/K-m is obtained by the projection from F(5) to a line with a center P is an element of F(5). By using this fact, we consider the field extension K/K-m from several point of view. [References: 7]
