Abstract
A base member includes a via having a first hole and a second hole. When viewed from a direction in which a base surface extends, the first hole and the second hole have shapes becoming wider as getting closer to a first surface and a second surface of the base surface from a portion at which a lower end of the first hole and an upper end of the second hole are in contact with each other. When the first hole and the second hole are viewed from the direction in which the base surface extends, a smaller angle of angles formed by a generatrix of the first hole and a generatrix of the second hole is smaller in a thin region of the base member than in a thick region of the base member.
