Title:
PHYSICAL QUANTITY DETECTING DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/037716
Kind Code:
A1
Abstract:
The objective of the present invention is to provide a physical quantity detecting device in which resonance of a cantilever-shaped part of a circuit board can be suppressed. The physical quantity detecting device is provided with: a circuit board 400 including a first support part 403 on which a physical quantity detecting element for detecting the physical quantity of a fluid is mounted and a second support part 460 on which a temperature detecting element for detecting the temperature of a fluid is mounted; and a molded housing 302 that is obtained by injection molding and that supports the circuit board 400, wherein the second support part 460 protrudes from an edge of the circuit board 400, and the temperature detecting element is disposed on a leading end part 700a forming a free end. The second support part 460 includes a third support part 701, 701a for supporting the second support part 460 so as to connect the second support part 460 to the housing 302 such that the third support part 701, 701a is closer to the leading end part 700a than a base end part 700b and is closer to the base end part 700b than a mounting part on which the temperature detecting element is mounted.
