Abstract
A substrate for a liquid jet recording head includes a plurality of built-in energy elements forming an array for generating thermal energy for ejecting liquid, built-in electrode wiring for supplying electric signals to the energy generating elements and first and second built-in temperature sensors disposed outside the array and adjacent opposite ends of the array for detecting a temperature of the substrate. First and second built-in heaters are disposed outside the array and adjacent opposite ends of the array for heating the substrate.
