The purpose of this invention is to obtain a physical-quantity detection device, the external shape of the housing of which can be reduced in size. Said physical-quantity detection device 300, which detects a plurality of physical quantities of a gas being measured 30 that flows through a main channel 124, is characterized by having a housing 302 positioned inside said main channel 124, a circuit board 400 insert-molded into said housing 302, and a plurality of detection sensors 452, 453, 454, 455, 456 mounted on both sides of the circuit board 400. |
