摘要：
In a substrate for an ink jet head used for an ink jet head recording apparatus, electrostatic breakdown of a diode sensor functional as a substrate temperature sensing element is prevented. A protective element is electrically connected between a diode sensor and an input/output pad for the diode sensor.
