Liquid jet head and liquid jet apparatus

A liquid jet head comprising:

• a jet hole plate including a jet hole array, the jet hole array including a plurality of jet holes each extending in a first direction, the jet holes side by side in a second direction perpendicular to the first direction;
• a head chip at one side in the first direction with respect to the jet hole plate and including channels communicating with the respective jet holes;
• a manifold at one side in a third direction perpendicular to the first direction and the second direction with respect to the head chip, the manifold configured to support the head chip by a first face facing the third direction and including a liquid flow path communicating with the channels;
• and
• a drive board supported on the first face of the manifold and electrically connected to the head chip.
