<p>Provided are a liquid jet head and a liquid jet apparatus in which it is possible to securely connect drawn wires and connection wires and to improve reliability. Connection portions 91 of drawn wires 90 drawn from piezoelectric elements 300 and pad portions 101 of a drive IC 100 for driving the piezoelectric elements 300 are connected by connection wires 110 formed by wire bonding and extended in directions intersecting drawing directions of the connection portions 91. The connection wires provided at least in a vicinity of an edge of the passage-forming substrate are longer than the connection wires provided in a central portion of the passage forming substrate. Accordingly, the connection wires 110 and the drawn wires 90 are suitably connected.</p> |
