Abstract
The present invention provides an ignition timing control device and an ignition system which are capable of performing ignition timing control that easily suppresses occurrence of knocking for internal combustion engine. An ignition timing control device has a knocking detection devicedetecting knocking of internal combustion engine; and an ignition timing adjustment deviceadjusting ignition timing of internal combustion engine according to a knocking signal obtained from knocking detection deviceand indicating knocking state and an externally-obtained signal concerning the ignition timing of the internal combustion engine. Knocking detection deviceand ignition timing adjustment deviceare electrically connected and formed integrally with each other. Ignition timing adjustment deviceis provided with a first connecting portioninputting the signal concerning the ignition timing and a second connecting portionoutputting the signal concerning the ignition timing that undergoes adjustment to a switching element
