Abstract
The present invention reduces, by optimizing disposition of components on an electronic circuit board, heat transfer from other components mounted on the same board, and improves measurement accuracy of an intake air temperature detection element. A physical quantity detection device of the present invention has an electronic circuit board, which is provided with one or more intake air temperature detection elements (elements having intake air temperature detection function), and which processes electric signals. Furthermore, the physical quantity detection device has a configuration wherein the intake air temperature detection elements, and a power supply regulator having the maximum heat generation quantity are mounted on the same electronic circuit board. The physical quantity detection device is characterized in that the intake air temperature detection elements are disposed on the air flow upstream side of the power supply regulator.
