Abstract
We propose a novel description for the Higgs mechanism by which a gauge boson acquires the mass in a manifestly gauge-invariant way. In the Higgs mechanism, we do not assume spontaneous breakdown of gauge symmetry signaled by a non-vanishing vacuum expectation value of the scalar field. The spontaneous symmetry breaking is sufficient but not necessary for the Higgs mechanism to work. This enables us to discuss the confinement-Higgs complementarity from a new perspective.
