To provide a thermal type element capable of determining a resistance value temperature coefficient of a temperature measuring resistor with a simple measurement.

A thermal element 10 comprises: a first temperature measuring resistor 3 for detection; a second temperature measuring resistor 5 for temperature coefficient measurement; and a diode 7. The first temperature measuring resistor 3 is arranged so as to be bridged over a cavity 1a formed on a semiconductor substrate 1. The second temperature measuring resistor 5 is arranged at a position different from the cavity 1a on the semiconductor substrate 1. The second temperature measuring resistor 5 has the same resistance value temperature coefficient as the resistance value temperature coefficient of the first temperature measuring resistor 3. The diode 7 is formed by a P-type region 7p+ and an N-type region 7n which are formed on the semiconductor substrate 1. The diode 7 is arranged at a lower part of the second temperature measuring resistor 5.
