PHYSICAL QUANTITY MEASURING DEVICE

摘要

A plate-shaped circuit board (7) configured to receive a detection signal from a detector (6) is housed in a case (1) and is held by a holder (9) with a flat substrate surface thereof intersecting with a bottom surface (3A) of a cover member (3). The holder (9) is attached to the cover member (3). The cover member (3) includes a cover body (30), and elongated supporting portions (31) projecting from the bottom surface (3A) of the cover body (30) into the case (1). The supporting portions (31) each include a pair of support projections (35) that support one of opposite side surfaces of the circuit board (7) along a projecting direction of the supporting portions. The holder (9) includes a flat portion (91) provided with engagement pieces (92) engageable with a second substrate (702).
