A liquid jet recording head has a recording element unit that has a recording element substrate, a flexible film member electrically connected to the substrate, a support member on which the substrate is fixedly held, and a support plate between the flexible film member and support member fixedly holding the flexible film member. Gates of the switching elements of the memory cells connected between one of the adjacently paired ones of the bit lines are respectively connected to different ones of the word lines. For the purpose of job-specific adaptation, the settings in the templates must be modified.
