    • A temperature detection circuit includes: a voltage generator that is connected to a first voltage line having first voltage and a second voltage line having second voltage and to output a third voltage to a third voltage line, the third voltage being obtained by transforming the first voltage to be stepped down as an ambient temperature becomes higher; and a detecting unit that includes: a delay section that is connected to the second voltage line and the third voltage line and to receive a pulse signal, the delay section being configured to output a delayed pulse signal that is obtained by delaying the pulse signal for a delay time set to be longer as the third voltage becomes lower; and a temperature detecting section that is configured to: receive the delayed pulse signal and the pulse signal; latch the delayed pulse signal based on the pulse signal; output the latched signal as a detection result.
