1. An anemometer using a thermal mass air velocity meter, comprising:
a substrate on which a circuit part is formed;
a heating element part configured to extend from a first side of the substrate and through which a heating element hole in which a heating element is installed is formed;
a pair of heating element soldering holes formed on a first side of the heating element part and spaced apart vertically so that a pair of leads of the heating element are connected;
a temperature sensor part configured to extend from the first side of the heating element part and through which a temperature sensor hole in which a temperature sensor is installed is formed; wherein the temperature sensor part comprises a first side and a second side; and
a pair of temperature sensor soldering holes formed on the second side of the temperature sensor part and spaced apart vertically so that a pair of leads of the temperature sensor are connected,
wherein the temperature sensor part comprises:
a first temperature sensor slit groove formed on the second side of the temperature sensor part, formed between the pair of temperature sensor soldering holes, and communicated with the temperature sensor hole.
