Document Type and Number:
Japanese Patent JP7067531
Kind Code:
B2
Abstract:
A housing includes a measurement passage through which a part of air flowing in a main passage flows. A sensor assembly is fixed on the housing and includes a circuit board. A detection element configured to output a signal in response to a flow rate of air flowing in the measurement passage and an electronic component configured to drive the detection element are mounted on the circuit board. An outer edge of the circuit board has a fractured part with a fractured shape and a cut part having a surface roughness smaller than that of the fractured part. The fractured part at the outer edge of the circuit board is not arranged in the measurement passage but provided at a position excluding the measurement passage.
