Abstract
An airflow meter includes a detecting element for detecting airflow rate, a control integrated circuit electrically coupled with the detecting element, a circuit board having a first surface and a second surface opposing each other, and having the control integrated circuit on the first surface, a heat sink arranged on a side of the second surface, and a shield part arranged between the circuit board and the heat sink. The heat sink has an electrically conductive property and is provided for removing heat from the control integrated circuit. In addition, the heat sink is floated from a ground. The shield part has an electrically conductive property and is electrically grounded.
