A power supply unit for an aerosol inhaler includes: a power supply able to discharge power to a load for generating an aerosol from an aerosol generation source； a temperature measuring unit configured to measure temperature of the power supply； and a control device configured to control first power or a first amount of power to be supplied to the power supply in a case where a measurement value of the temperature measuring unit is equal to or higher than a first threshold, to a value smaller than second power or a second amount of power to be supplied to the power supply in a case where the measurement value is lower than the first threshold.一種霧氣吸嚐器用電力供應單元，包括：電力供應器，其能夠放電給用於從霧氣產生源產生霧氣的負載；溫度測量單元，其經組配成測量該電力供應器的溫度；以及控制裝置，其經組配成控制在該溫度測量單元之測量值等於或高於第一臨界值的情形下要供應至該電力供應器之第一電力或第一電量為小於在該測量值低於該第一臨界值的情形下要供應至該電力供應器之第二電力或第二電量之數值。
