Claim 0:
1. An inhalation component generation device, comprising:
a load configured to vaporize or atomize an inhalation component source with electric power from a power supply; and
circuitry configured to
acquire a voltage value of the power supply; and
perform at least one of: a degradation diagnosis function that estimates or detected that the power supply is degraded; and a failure diagnosis function that estimates or detects that the power supply is failed based on a time period, which is measured by a timer, required for the voltage value of the power supply to reach an upper limit from a lower limit of a predetermined voltage range during charging of the power supply, wherein

the circuitry is configured to not simultaneously perform the failure diagnosis function and the degradation diagnosis function,
an upper limit of the predetermined voltage range for the failure diagnosis function is smaller than a lower limit of the predetermined voltage range used for the degradation diagnosis function,
a lower limit of the predetermined voltage range for the failure diagnosis function is lower than a discharge termination voltage of the power supply and is larger than a lower limit of an operational voltage of the circuitry, and
the timer is activated in the failure diagnosis function when the voltage of the power supply reaches the lower limit of the predetermined voltage range for the failure diagnosis function during charging of the power supply.
