A diagnosis apparatus performing a diagnosis for reuse of an electric storage apparatus including a plurality of electric storage elements connected electrically in series includes a voltage sensor detecting a voltage of each of a plurality of blocks, the plurality of electric storage elements being divided into the blocks; a current sensor detecting a current in the electric storage apparatus; and a controller calculating an internal resistance of each of the blocks based on outputs from the voltage sensor and the current sensor. The controller specifies the highest of the internal resistances of the plurality of blocks as a criterion to perform the diagnosis for the reuse of the electric storage apparatus.
