  We discuss the properties of the topological soliton, or the
Electroweak-Skyrmion, in the system of the Standard Model Higgs Lagrangian with
addition of general O(p^4) terms. We show that the upper bound on the mass of
the Electroweak-Skyrmion is about 10 TeV, which is obtained from currently
available experimental constraints on coefficients of O(p^4) terms. The impact
on the properties of the Electroweak-Skyrmion due to further modification of
the Lagrangian is also discussed, and comments on possible mechanisms for the
generation of the Electroweak-Skyrmion in the early Universe as a dark matter
are given.
