A semiconductor integrated circuit device includes a first clock domain having a plurality of first flip-flops which is configured to operate with a high-speed clock; a second clock domain having a plurality of second flip-flops, composed of a third flip-flop and a plurality of fourth flip-flops, which is configured to operate with a low-speed clock; and a test clock supplying section configured to supply, at a time of delay fault test for the second clock domain, a test clock based on the high-speed clock to the third flip-flop to which data from the first clock domain is input, and not to supply the test clock to the plurality of fourth flip-flops.
