    摘要： An ink jet head has a head substrate including discharge elements for discharging ink, with an electric wiring board being electrically connected to the head substrate, in which the periphery of the head substrate is sealed with a first sealant, and an electric splice between the head substrate and the electric wiring board is sealed with a second sealant. The first and second sealants contain the same base resin and curing agent, and the second sealant shows higher hardness than the first sealant after curing. This ink jet head is free from problems such as cavities and fissures at the boundary of the two sealants caused by a difference in linear expansion coefficients.
