Abstract.
Let K be an imaginary quadratic field of discriminant 
.
We deal with problems of constructing normal bases between abelian
extensions of K by making use of singular values of Siegel
functions. First, we find normal bases of ring class fields of
orders of bounded conductors depending on dK over K by using a
criterion deduced from the Frobenius determinant relation. Next,
denoting by 
the ray class field modulo N of K for an
integer 
we consider the field extension
for a prime 
and a positive integer
m relatively prime to p and then find normal bases of all
intermediate fields over 
by utilizing Kawamoto's
arguments. We further investigate certain
Galois module structure of the field extension
with 
, which would be an
extension of Komatsu's work.
