A battery diagnostic apparatus and a battery diagnostic method that are capable of accurately determining a deteriorated state of a battery and enabling use of the battery immediately before or near the end of the battery life are provided. The battery diagnostic apparatus includes a power supply monitoring unitconfigured to detect that a power supply voltage has changed from less than a predetermined voltage to equal to or more than the predetermined voltage, and a controllerconfigured to measure a battery voltage in a predetermined period after the detection that the power supply voltage is equal to or more than the predetermined voltage, calculate electric power associated with a remaining capacity of the batterybased on the battery voltage, and perform deterioration determination of the batterybased on the electric power associated with the remaining capacity of the battery

Radio equipment includes a substrate on which a first antenna for near field communication is provided, a base portion on which the substrate is erected, and a cover portion configured to be attached to the base portion so as to cover the substrate. The cover portion includes an opposing portion configured to oppose the first antenna and a non-opposing portion disposed closer to the base portion than the opposing portion in a direction in which the substrate is erected. A distance from an outer surface of the cover portion to the substrate at the opposing portion is shorter than a distance from the outer surface of the cover portion to the substrate at the non-opposing portion.
