Abstract
When cleaning is performed to remove kogation, which is deposited on a heat acting portion, by causing an electrochemical reaction through application of a voltage between an upper electrode and an opposing electrode, a wiring located at a periphery of the opposing electrode occludes hydrogen generated during the cleaning, thereby causing hydrogen embrittlement. A unit configured to heat the wiring connected to the opposing electrode is provided, and is driven during the cleaning or after the cleaning, to thereby force hydrogen out of the wiring. Thus, the hydrogen embrittlement of the wiring is suppressed.
