1. A memory card comprising:
a memory chip;
a controller chip;
a sealing portion that houses the memory chip and the controller chip and that includes a first main surface and a second main surface arranged on an opposite side of the first main surface;
a first terminal group that includes a plurality of electrode terminals arranged in a first direction inside the first main surface;
a second terminal group that includes a plurality of electrode terminals arranged in the first direction inside the first main surface; and
a conductive pattern that is arranged between the first terminal group and the second terminal group in the first main surface, that has a longer dimension than a dimension of the electrode terminal in the first terminal group, that has a longer dimension than a dimension of the electrode terminal in the second terminal group, and that has a planar shape,
wherein:
the conductive pattern is arranged at a region overlapping with the controller chip when viewed in a third direction perpendicular to the first main surface,
the conductive pattern is arranged so as to cross the controller chip in the first direction when viewed in the third direction, and
the conductive pattern is arranged so as to be crossed in a second direction by the controller chip when viewed in the third direction, the second direction being a direction perpendicular to the first direction in a planar view.
