PROBLEM TO BE SOLVED: To provide a fuse which will not cause malfunction due to the affection of a using atmosphere and the material of an attacking object while durable against a bad transporting environment. SOLUTION: A detonating circuit 4 ignites a shaped bursting charge at a time when a detonating signal, outputted from the fuse not shown in a diagram, is inputted. A distance measuring unit 6 obtains a beat frequency Fv from a difference between the frequency Fb of an electric signal S1 (or a reflecting wave) inputted from a radar and the frequency F of the radiation wave to obtain a distance Ls between the attacking target. An arithmetic operating unit 7 compares the data of the distance Ls inputted from the distance measuring unit 6 with the data of distance Lp for igniting the shaped bursting charge, which is read out of a memory circuit 8. The memory circuit 8 stores the data of distance Lp of the optimum stand-off position for bursting the bursting charge, not shown in a diagram, in accordance with the target while the data is outputted to the operating unit 7 as an electric signal S3.
