PROBLEM TO BE SOLVED: To provide a battery pack detecting blowout of a fuse inexpensively with high reliability without using an expensive fuse having a blowout detection function. SOLUTION: A battery pack 4a is configured by connecting a plurality of battery arms 3a (3b) in parallel, wherein the battery arm includes one or more battery cells 1a (1b) and fuses 2a (2b) serially connected to each other. The battery pack includes: voltage detectors 5a, 5b as a voltage information-acquiring part for acquiring voltage information from the plurality of battery arms 3a (3b), respectively; and a subtractor 6 and a level determination unit 7 as detection parts for detecting the blowout of the fuses 2a, 2b based on the voltage information obtained by the voltage information acquiring part (the voltage detectors 5a, 5b).
