To provide an ignition notifying device that notifies a farm field administrator that a combustion device is ignited and burns after the startup of an automatic ignition device.

The ignition notifying device A is provided in the automatic ignition device B in which an ignition tool 1 is electrified with a current from an electrical power source 3 actuated by the detection of a preset temperature by a temperature sensor 2, and the combustion device installed in a farm field is ignited by the Joule heat generated in the ignition tool 1 and burns to prevent farm products from being damaged by frozen frost damage. The ignition notifying device includes a push type electromagnetic solenoid 13 that is operated by the energization from the electrical power source 3 actuated by the detection of a dangerous-level temperature by the temperature sensor 2, and a mobile phone 14 that is operated by a push rod 13a of the push type electromagnetic solenoid 13 to transmit the startup of the automatic ignition device B to a telephone 15 of the farm field administrator.
