A semiconductor device, comprising: a user circuit having a plurality of flip-flops; and a connection path which, while in test mode, connects the plurality of flip-flops and forms a scan chain, wherein the connection path has a logic operation circuit which performs a logic operation on a non-inverted output value of any flip-flop among the plurality of flip-flops and outputs the result, or, an inverted value connection path which outputs to a following-stage flip-flop an inverted output value of any flip-flop among the plurality of flip-flops.
