PROBLEM TO BE SOLVED: To provide a liquid discharge head which detects a temperature close to a temperature of a liquid actually discharged.SOLUTION: A liquid jet head 1 includes: a liquid compression plate 2 including a substrate end surface Ta, a substrate side surface Tb intersecting with the substrate end surface Ta, and multiple channels C which open on the substrate end surface Ta and apply pressure to a liquid; a support frame 3 fixed to the substrate side surface Tb; and a temperature sensor 4 which contacts with the support frame 3. The temperature sensor 4 contacts with the support frame 3 and thus is able to detect an averaged temperature of the liquid actually discharged. |
