PROBLEM TO BE SOLVED: To provide a semiconductor integrated circuit technique in which, even if elements are fined,α-rays-resistant intensity of a flip-flop circuit is not lowered. SOLUTION: A data holding circuit (100) is structured by at least three flip- flop circuits (FF1 to FF) which input the same signal, and a majority logic circuit (MJR) which outputs a signal corresponding to a threshold value occupied in a majority or more out of these outputs of the flip-flop circuits.
