Document Type and Number:
Japanese Patent JP7503026
Kind Code:
B2
Abstract:
An electronic device includes a substrate and circuitry mounted thereon. In plan view in a thickness direction of the substrate, the first conductive portion includes a rounded convex corner, and the second conductive portion includes a concave corner facing the convex corner. Extensions of two straight lines contiguous to the convex corner intersect at a first apex of a convex angle. Extensions of two straight lines contiguous to the concave corner intersect at a second apex of a concave angle. A distance between a convex corner point and a concave corner point is greater than a distance between the first apex and the second apex, where the convex corner point is an intersection of a corner line passing through the first apex and the second apex, and the convex corner, and the concave corner point is an intersection of the corner line and the concave corner.
