Abstract: In an electronic component, a package includes a resin portion and a plurality of land electrodes. The resin portion has a first main surface and a second main surface facing each other in a predetermined direction and covers an IC chip. The plurality of land electrodes includes one first land electrode and three or more second land electrodes, which are the remaining land electrodes other than the first land electrode. The area of the first land electrode is larger than the area of each of the three or more second land electrodes in plan view from the predetermined direction. The plan-view shape of the first land electrode is different from the plan-view shapes of the three or more second land electrodes in plan view from the predetermined direction.
