摘要:
A wheeze detection device that allows suppressing a noise and improving detection accuracy of wheezing. The device includes a first microphone configured by a MEMS microphone, a space-forming member (a first housing, an O-ring, a flexible circuit board, and a second housing) forming an accommodation space that accommodates the first microphone, and a housing cover that forms a pressure receiving unit that closes the accommodation space and receives a pressure from a body surface. The space-forming member has a hole portion connected to an atmosphere. The accommodation space is connected to the atmosphere via the hole portion. The hole portion includes branch portions to between a groove and a terminal and two branched hole portions branched at each branch portion from a side of the groove. One branched hole portion among the two branched hole portions is connected to the terminal. The other branched hole portion is closed.
