Measurement of the Higgs self-coupling at JLC
  We examine the double Higgs production process at JLC. We focus our attention on the measurement of the Higgs self-coupling. The sensitivity of the triple Higgs coupling measurement is discussed in the Higgs mass range 100-200 GeV and the center of mass energy to be 500 GeV-1.5 TeV.
