  We study wavefunctions on D$7$-branes with magnetic fluxes in the conifold.
Since some supersymmetric embeddings of D-branes on the $AdS_5\times T^{1,1}$
geometry are known, we consider one of the embeddings, especially the spacetime
filling D$7$-branes in which (a part of) the standard model is expected to be
realized. The explicit form of induced metric on the D$7$-branes allows us to
solve the Laplace and Dirac equations to evaluate matter wavefunctions in extra
dimensions analytically. We find that the zero-mode wavefunctions can be
localized depending on the configuration of magnetic fluxes on D$7$-branes, and
show some phenomenological aspects.
