    摘要： A leak detection device includes a pulse signal outputting portion that outputs predetermined pulse signals to a positive connecting wire connected to a positive side of a battery and a negative connecting wire connected to a negative side of the battery; a response waveform detecting portion that detects a positive response waveform for the pulse signal output to the positive connecting wire and a negative response waveform for the pulse signal output to the negative connecting wire; an amplitude ratio calculating portion that calculates an amplitude ratio based on the positive response waveform and the negative response waveform; and a leak detecting portion that detects a leak between the battery and a ground based on the amplitude ratio.
