Abstract
To provide an electronic device that can detect an abnormality in an element with a simple configuration. An electronic device 1 includes: a first element string group 21 formed by at least one element string 211 to 21m connected in parallel, the element string 211 to 21m being formed by at least one element connected in series; a second element string group 22 formed by the element string 221 to 22n being at least one in number and connected in parallel; and an abnormality detecting unit 4 that detects an abnormality in the element string 211 to 21m and 221 to 22n forming at least one of the first element string group 21 and the second element string group 22, based on whether or not a first current I21 being the sum of current flowing through the element string 211 to 21m forming the first element string group 21 and a second current I22 being the sum of current flowing through the element string 221 to 22n forming the second element string group 22 satisfy a prescribed relationship.
