Liquid discharge head having movable member with corrosion-resistant coating and method of manufacture therefor

A method for manufacturing a liquid discharge head provided with a discharge port for discharging liquid;

• a liquid flow path communicating with said discharge port in order to supply said liquid to said discharge port;
• a substrate having a heat generating member for creating a bubble in said liquid;
• a movable member arranged in said liquid flow path, having a free end on said discharge port side to face said heat generating member;
• and a pedestal portion to support said movable member to said substrate, said method comprising the steps of:
• forming said pedestal portion on said substrate in a specific configuration;
• forming said movable member in a predetermined position on said substrate, including a portion formed on said pedestal portion, using a same material as said pedestal portion;
• and
• covering said movable member with a coating member having a higher resistance to corrosion than the material forming said movable member.
