An -dimensional locally conformal Kähler manifold (l.c.K-manifold) is characterized as a Hermitian manifold admitting a global closed -form (called the Lee form) whose structure satisfies ,
where denotes the covariant differentiation with respect to the Hermitian metric , , and the indices run over the range .
For l. c. K-manifolds, I. Vaisman  gave a typical example and T. Kashiwada (,
,) gave a lot of interesting properties about such manifolds.
In this paper, we shall study certain properties of l. c. K-space forms. In , we shall mainly get the necessary and sufficient condition that an l. c. K-space form is an Einstein one and the Riemannian curvature tensor with respect to will be expressed without the tensor field . In , we shall get the necessary and sufficient condition that the length of the Lee form is constant and the sufficient condition that a compact l. c. K-space form becomes a complex space form. In the last , we shall prove that there does not exist a non-trivial recurrent l. c. K-space form.
