To obtain a physical quantity detection apparatus that can reduce the outer shape of a housing in size. A physical quantity detection apparatus 300 detects a plurality of physical quantities of gas 30 to be measured flowing in a main passage 124. The physical quantity detection apparatus 300 has a housing 302 disposed in the main passage 124, a circuit substrate 400 insert molded in the housing 302, and a plurality of detection sensors 452, 453, 454, 455, and 456 each mounted on each of one face and the other face of the circuit substrate 400.
A physical quantity detection apparatus that detects a plurality of physical quantities of gas to be measured flowing in a main passage, the apparatus comprising:
An electronic apparatus including a circuit substrate and a housing in which the circuit substrate is insert molded, wherein the housing has a fluid admitting section and a fluid exiting section formed on the side of one of the principal faces of the circuit substrate, a path connecting the fluid admitting section and the fluid exiting section is a fluid passage, and on at least one cross section substantially perpendicular to the fluid passage, resins forming the housing are formed on both sides of the principal faces of the circuit substrate.
