An element is protected without hampering an actual operation in the case where overvoltage that might damage the element is applied. A semiconductor device includes a first potential supply terminal 100; a second potential supply terminal 101; a protection circuit 107 which includes a voltage divider 102 electrically connected to the first potential supply terminal 100 and the second potential supply terminal 101, a control circuit 103, and a bypass circuit 106; and a functional circuit 108 which is electrically connected to the first potential supply terminal 100 and the second potential supply terminal 101 through the protection circuit 107.
