For analytic functions f (z) normalized by f (0) = 0 and f 0 (0) = 1 in the open unit disk U, a new subclass S of f (z) concerning with spirallike functions in U is introduced. The object of the present paper is to discuss an extremal function for the class S and coe¢ cient estimates of functions f (z) belonging to the class S.
