<P>PROBLEM TO BE SOLVED: To provide a liquid jet head and a liquid jet device in which heat radiation of a driving element is efficiently performed and thus, size and cost of the driving element can be reduced, durability of the driving element is improved, an influence on the temperature of a liquid is reduced as far as possible, and liquid jet characteristics can be improved. <P>SOLUTION: The liquid jet head includes: a piezoelectric element unit 18 having a heat conductive member 35; a case head 20 with an accommodating part 19 in which the piezoelectric element unit is accommodated; and a flexible print board 50 which is connected to the piezoelectric element and on which the drive element 60 for driving the piezoelectric element is mounted. Further, a Peltier element 61 is disposed in the accommodating part of the case head so that a heat absorption face 61A of the Peltier element 61 is made to face the drive element and heat of a heat generation face 61B of the Peltier element 61 is radiated through a heat radiation member whose one end faces the external of the case head. <P>COPYRIGHT: (C)2012,JPO&INPIT |
