ABSTRACT:
A method for manufacturing a liquid jet head is provided, which includes: a preparation step of preparing a substrate array which is provided with a first substrate having formed therein a first flow path, a second substrate bonded to one side of the first substrate and having formed therein a second flow path, and a separation layer partitioning the first flow path and the second flow path; a sealing step of sealing the first flow path by adhering a sealing film onto a side of the first substrate opposite to the second substrate using an adhesive layer; and a removal step of removing the separation layer after the sealing step is performed, wherein in the removal step, the separation layer is removed in a state in which an internal pressure of the first flow path is lower than an external pressure.
