Abstract
The objective of the present invention is to obtain a flow rate measurement device capable of reducing variations in the flow rate detection accuracy by suppressing the inclination of a chip package relative to a circuit board. A flow rate measurement deviceof the present invention includes a chip packagehaving a flow rate sensorand a passage wallformed therein, and a circuit boardon which the chip packageis mounted, in which the chip packageis mounted such that the flow rate sensorfaces a portion of the circuit boardand a portion of the passage wallas a resin portion of the chip packagecontacts the circuit board
