1. An analyzing device comprising:
- a sensor section comprising a reagent layer including a reagent that reacts with a substance in a sample liquid, an electrode including a first electrode and a second electrode for applying a voltage to the reagent layer, and an external layer membrane for making contact with the reagent layer;
a voltage application unit for applying across the first electrode and the second electrode at least one of a first voltage that obtains a response caused by the substance and a second voltage that either obtains no response or substantially no response caused by the substance;
a current measurement unit for measuring current flowing between the first electrode and the second electrode; and
a determination unit for determining whether or not there is a defect present in the external layer membrane based on at least one of a first physical quantity related to an amount of change per specific period of time of a first current measured by the current measurement unit when the first voltage has been applied and a second physical quantity related to an amount of change per specific period of time of a second current measured by the current measurement unit when the second voltage has been applied.

Abstract
There is provided a sensor testing method including: applying at least one of a first voltage that obtains a response caused by a substance and a second voltage that either obtains no response or substantially no response caused by the substance across a first electrode and a second electrode of a sensor; measuring current flowing between the first electrode and the second electrode; and determining whether or not there is a defect present in the sensor based on a quantity related to an amount of change per specific period of time of a current measured when the first voltage and/or the second voltage have been applied.
