Document Type and Number:
WIPO Patent Application WO/2019/064908
Kind Code:
A1
Abstract:
The present invention is to obtain a physical quantity detection device capable of suppressing thermal influence which is exerted on a sensor and caused by miniaturization. A physical quantity detection device 20 of the present invention is provided with: a chip package 208 in which a flow rate sensor 205 and electronic components are sealed with a resin; and a circuit board 207 on which the chip package 208 is mounted. The chip package 208 is fixed to the board surface of the circuit board 207 while a portion of the chip package protrudes laterally from an end portion of the circuit board 207. The circuit board 207 has a flat blank space region S which is wider than the width of the chip package 208 at a position on the board surface and at a position deviated in a direction opposite to the protrusion direction of the chip package 208.
