PROBLEM TO BE SOLVED: To provide a thermal printing head which can be surely prevented from getting in an abnormal high-temperature state. SOLUTION: The thermal printing head A1 includes a substrate 1, a heating resistor 2 formed on the substrate 1, a driving IC 3 controlling energizing of the heating resistor 2, and a thermistor element 4 attached to the substrate 1. The driving IC 3 is provided with a strobe signal terminal 31 making the heating resistor 2 generate heat when voltage higher than a threshold is applied thereto, and one terminal of the thermistor element 4 is connected to the strobe signal terminal 31.
