摘要：
An ink jet head having a plurality of heat generating resistive elements (3) arranged in an array for discharging ink, comprises a base board having said heat generating resistive elements (3) and a plurality of layers for electrical insulation or protection laminated on a substrate (1) and liquid paths on said base board corresponding to said heat generating resistive elements.
At least a part of said layers is removed between said heat generating resistive elements (3) adjacent to each other.
At least a part of said layers is removed between said heat generating resistive elements (3) adjacent to each other.
