Flow rate measurement device

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 device 20 of the present invention includes a chip package 310 having a flow rate sensor 311 and a passage wall 314 formed therein, and a circuit board 300 on which the chip package 310 is mounted, in which the chip package 310 is mounted such that the flow rate sensor 311 faces a portion of the circuit board 300 and a portion of the passage wall 314 as a resin portion of the chip package 310 contacts the circuit board 300.
