The invention a semiconductor device and a measurement device that have improved manufacturing efficiency and enable the connection of an integrated circuit and a lead frame to be easier. The semiconductor device includes: an oscillator including external terminals disposed on a first face with a specific distance along a first direction; the integrated circuit including a first region formed with first electrode pads along one side, and a second region formed with second electrode pads on two opposing sides of the first region; and the lead frame that includes terminals at a peripheral portion, and on which the oscillator and the integrated circuit are mounted such that the external terminals, the first and second electrode pads face in a substantially same direction and such that one side of the integrated circuit is substantially parallel to the first direction, and the lead frame having terminals at the periphery.
