Patent ID: 7649235

Claim:
An electronic component package comprising: a mounting board having a surface; an external electrode disposed on said surface of said mounting board; an electronic component connected to said mounting board via said external electrode, said electronic component having a component-substrate composed of a piezoelectric body and having a first surface, a second surface opposing said first surface, and an outer end surface, a device disposed on said first surface of said component-substrate, a component-cover made of silicon and having an outer end surface, said component-cover covering said device and said first surface of said component-substrate, an adhesive portion between said component-substrate and said component-cover, and a protector composed of a resin including filler and having an outer end surface, said protector covering said second surface of said component-substrate and having a coefficient of elasticity of at least 5 GPa, wherein said outer end surfaces of said component-substrate, said component-cover, and said protector are coplanar, and wherein said component-substrate and said component-cover are bonded via said adhesive portion by an interatomic bond; and a molding resin covering said electronic component.
