  An effective Lagrangian for the technidilaton and its interactions with
matter is constructed. Properties of the technidilaton are compared with those
of the Higgs boson. Technidilaton decays and production channels are
investigated. Main technidilaton decays are suppressed compared to the Higgs
boson and the most important production mechanism is due to gluon fusion.
Prospects for technidilaton production and detection at $e^+e^-$ colliders and
the SSC are examined. LEP 1, LEP 2 and SSC can find or rule out a technidilaton
with a mass up to $10~GeV$, $40~GeV$ and $230~GeV$ respectively.
