  The dual Meissner effect is observed without monopoles in quenched SU(2) QCD
with Landau gauge-fixing. Abelian as well as non-Abelian electric fields are
squeezed. Magnetic displacement currents which are time-dependent Abelian
magnetic fields play a role of solenoidal currents squeezing Abelian electric
fields. Monopoles are not always necessary to the dual Meissner effect. The
squeezing of the electric flux means the dual London equation and the
massiveness of the Abelian electric fields as an asymptotic field. The mass
generation of the Abelian electric fields is related to a gluon condensate
$<A^a_{\mu}A^a_{\mu}>\neq 0$ of mass dimension 2.
