Judicial system is very important in liberal democracy. But existing comparative studies of liberal democracy including Lijphart(1984)model does not analyze judicial system sufficiently. In this article I analyze it. To be concrete, I examine relationship democracy types("pluralism vs.corporatism"index, "majoritarian democracy vs.consensus democracy"index and complex index of Lijphart and Crepaz(1995))and judicial system(legal systems, court systems and lawyer population). I find first that there is interrelation between legal systems and various democracy types, second that court systems have weak relationship with democracy types, but adoption of the jury system have little relation with democracy types, third that lawyer population and democracy types are correlated. Consensus and corporatstic democracies tend to have less lawyer population.
