ABSTRACT:
Since an electronic device comprises an electronic component, an external connection terminal electrically connected to the electronic component, and an envelope for sealing the electronic part and having a thickness less than about 0.5 mm, the electronic device is miniaturized even in the case where it is provided with a large number of terminals. Further, since the electronic component is sealed by the envelope, moisture, etc. is not admitted into the electronic component, resulting in high reliability. In addition, since the thickness of the envelope is thin, the external terminal can be shortened. Thus, the inductance or capacitance of this terminal can be reduced.
