Baryogenesis in the early universe requires a new source of CP violation beyond that in the CKM model. Perhaps the most promising place to look is in the Higgs sector. Though the Standard Model predicts that the couplings of the Higgs boson are exactly CP-conserving, more general models of the Higgs sector give many opportunities for CP violation. This talk will discuss the expectations for searches for these CP-violating couplings in the high-precision study of the Higgs boson at the International Linear Collider (ILC).
