Claim 17:
18. An in-vehicle wireless electric power feeding device that is used in a vehicle wirelessly performs electric power feeding to an electric power reception device and stops the electric power feeding at a temperature not lower than or higher than a predetermined first temperature threshold, the in-vehicle wireless electric power feeding device comprising:
an electric power transmitter configured to wirelessly perform electric power feeding to the electric power reception device;
a temperature measurement device configured to measure a temperature of the electric power transmitter; and
circuitry configured to control the electric power transmitter so that the electric power transmitter wirelessly performs electric power feeding to the electric power reception device when the temperature measured by the temperature measurement device at startup is not higher than or lower than a predetermined second temperature threshold higher than the first temperature threshold,
wherein the circuitry is configured to perform a startup time electric power feeding mode for wireless performing electric power feeding to a smartphone, wherein the circuitry for performing the startup time electric power feeding mode is configured to
wirelessly perform electric power feeding to the smartphone when the temperature measured by the temperature measurement device at the startup of the in-vehicle wireless electric power feeding device is not higher or lower than the second temperature threshold, wherein the second temperature threshold is higher than the first temperature threshold, and
control the electric power transmitter so that the electric power transmitter does not wirelessly perform electric power feeding to the smartphone when the temperature measured by the temperature measurement device at the startup is higher than the second temperature threshold or not lower than the second temperature threshold,

wherein, in response to the electric power feeding to the smartphone being wirelessly performed at the startup, the circuitry is configured to control the electric power transmitter so the electric power transmitter
continues the electric power feeding after the temperature measured by the temperature measurement device becomes lower than a third temperature threshold hold or not higher than the third temperature threshold during the electric power feeding, or
stops the electric power feeding when the temperature measured by the temperature measurement device during the electric power feeding becomes higher than the first temperature threshold or becomes not lower than the first temperature threshold, and

controls the electric power transmitter so that the electric power transmitter resumes the electric power feeding when the temperature measured by the temperature measurement device becomes lower than the third temperature threshold which is lower than the first temperature threshold while the electric power feeding is stopped.
