In a shielding configuration of a chip part, a shielding effect and a cooling effect are sufficiently obtained at the same time. In an electronic device including a chip part to be disclosed, a shielding conductor includes a ceiling plate section covering the chip part and side plate sections which are formed to be united with the ceiling plate section and to be at a position lower than the ceiling plate section and which are arranged on both sides in a horizontal direction of the chip part, and openings are formed in both side ends in a front-rear direction of the shielding conductor to open both sides in a front-rear direction of the chip part, and the side plate sections of the shielding conductor are electrically connected via a plurality of shielding bumps in the front-rear direction to a ground layer pattern of a mounting substrate.
