  We consider the entanglement entropy in the dS/CFT correspondence.In Einstein
gravity on de Sitter spacetime we propose the holographic entanglement entropy
as the analytic continuation of the extremal surface in Euclidean anti-de
Sitter spacetime.Even though dual conformal field theories for Einstein gravity
on de Sitter spacetime have not been known yet,we analyzed the free $Sp(N)$
model dual to Vasiliev's higher spin gauge theory as a toy model.In this model
we confirmed the behaviour similar to our holographic result from Einstein
gravity.
