PROBLEM TO BE SOLVED: To miniaturize a voltage detector for detecting a battery voltage.SOLUTION: A voltage detector 1 includes: a voltage detection circuit 30, provided for each of a plurality of battery cell group which configures a battery B, for detecting the voltage of the battery cell group; and a control circuit 80, which is insulated to the voltage detection circuit 30, for controlling the battery B based on the voltage. The voltage detector 1 further includes: a control circuit substrate 6 on which the control circuit 80 is loaded; a first communication element 25 loaded on the control circuit substrate 6; a voltage detection circuit substrate 7 on which the voltage detection circuit 30 is loaded and which is disposed in parallel to the control circuit substrate 6; a second communication element 26 which is loaded on the voltage detection circuit substrate 7 and communicable with the first communication element 25 in a non-contact manner. The first communication element 25 and the second communication element 26 are disposed in a manner to face each other. |
