ABSTRACT:
A semiconductor device, comprising a semiconductor chip; a pad electrode; an electrode portion; a wiring portion. An insulating portion is formed from electrically insulating material, covering the surface of the semiconductor chip and sealing the sensor element, wiring portion and electrode portion, in a state which exposes at least the electrode portion on the surface of the semiconductor chip. The electrode portion is placed in a position which does not overlap with the sensor element in the thickness direction of the semiconductor chip.
