  We introduce a D7-brane probe in AdS_5 x S^5 background in a way that the 4d
part of the induced metric on D7-brane becomes 4d de-Sitter space (dS_4) inside
AdS_5 instead of 4d Minkowski space. Although supersymmetry is completely
broken, we obtain a static configuration and show the absence of dynamical
tachyonic modes. Following holographic renormalization we renormalize the
Dirac-Born-Infeld action of D7-brane and we completely fix the counter terms
including finite contributions from the consistency under various limits.
Through the AdS/CFT correspondence we study the chiral condensate and meson
spectrum of CFT dual theory on dS_4 where the energy scale is identified with
the direction normal to dS_4 space in AdS_5. We identify and properly reproduce
the finite temperature effects on dS_4. Our results support the holographic
interpretation of the Randall-Sundrum model with non fine-tuned dS_4 brane(s)
and the holography between AdS_p (or dS_p) bulk gravity and CFT on dS_{p-1}
called the (A)dS/dS correspondence.
