PROBLEM TO BE SOLVED: To provide a judgment device capable of judging knocking sensor connection condition. SOLUTION: An engine ECU which is a device for judging a knocking sensor connection condition executes a program including a step S106 calculating a knocking sensor mounting position A closest to a cylinder in which fuel is injected next, a step S114 calculating an input part B to which the knocking sensor outputting the maximum peak value P during a gate open section during which signal of fuel injection completion timing is acquired is connected, a step S120 judging that the knocking sensor connection condition is abnormal when the input part B is not detected if the same corresponds to a mounting position A in all gate section (No in S118), and a step S124 changing corresponding relation of the mounting position and the input part to make the mounting position corresponding to the detected input part B to the mounting position A if the mounting position A does not correspond.
