In the standard model of elementary particle physics,
the Higgs boson which is discovered last year plays a key role to understand the origin of mass of elementary particles.
We know that top quark is the heaviest particle in elementary particles discovered ever.
The large top quark mass indicates that the top quark should couple with the Higgs boson in the strong coupling.
Since the standard model in the particle physics can not explain the large top quark mass,
it is important to attempt to understand simultaneously both the top quark and the Higgs boson in a framework beyond the standard model.
In this talk, I would like to talk about the top quark and Higgs boson mass from the viewpoint of a dynamical electroweak symmetry breaking model.
