The hypothesis examined in the present study is whether SES variables have not only direct causal effect upon political participation but also indirect causal effects mediated by political attitudes in a wide sense. This hypothesis was tested in a nation-wide survey, conducted in December, 1975 (N=2164). The results are as follows: (a) Among SES variables, education has the strongest direct and indirect causal effects upon political participation. (b) Occupation has a rather strong direct causal effect upon political participation, but has weak indirect effects. (c) Income has a weak direct causal effect upon political participation, but has strong indirect causal effects resulting to influence political attitudes, and thus leading to influence political participation.
