Claim Text:
1. A voltage monitoring module comprising: m (m is an integer equal to or greater than 2) input terminals respectively connected to high-potential-side terminals of m battery cells connected in series; a ground terminal that receives a voltage of a low-potential-side terminal of a lowermost battery cell of the m battery cells; (m−1) voltage control circuits that are each connected between two adjacent input terminals of the m input terminals and cause a current to flow to generate a predetermined voltage drop when a voltage of a k-th (k is an integer equal to or greater than 2 and equal to or less than m) input terminal counted from a high potential side is higher than a voltage of a (k−1)-th input terminal counted from the high potential side; and a disconnection detection circuit that detects a disconnection between each of the high-potential-side terminals of the m battery cells connected in series and each of the m input terminals, wherein the disconnection detection circuit comprises:
