PHYSICAL QUANTITY DETECTION DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a physical quantity detection device which achieves improvement in appearance quality of a circuit board and high thermal responsiveness.SOLUTION: A physical quantity measurement device includes: a circuit board made of a printed circuit board to which at least one detection part for detecting physical quantity of a measured gas passing through a main passage and a circuit part for performing operation processing on the physical quantity detected by the detection part are provided; and a housing for storing the circuit board. Color tones of a resist film 704 formed on a surface of the circuit board and a resin sheet member configurating a layer are dark.SELECTED DRAWING: Figure 5-2
