A liquid discharge head has a plurality of first liquid flow passages connected to outlets for discharging the discharge liquid, a plurality of second liquid flow passages having an element board with heating elements for generating a bubble in the bubbling liquid and corresponding to the first liquid flow passages, and movable separation films substantially and mutually separating the first liquid flow passages and the second liquid flow passages at all times, wherein the movable separation films are mutually independent individual separation films for each of the second liquid flow passages. It is possible to directly provide a flow passage wall configuring a side wall of a first liquid flow passage onto the element board by the low temperature junction by using surface activation since the movable separation films are individual separation films. The junction of the flow passage wall to the element board is surely performed and the dispersion in discharge characteristics depending on the lot of products can be restrained.
