Package including lead component having recess

A package comprising:

• a first electrode and a second electrode whose polarity is different from that of the first electrode, and at least one of the first electrode and the second electrode has an outer lead component defining a recess that is recessed from a distal end surface of the outer lead component in plan view, an inner surface of the recess being plated and the distal end surface of the outer lead component being not plated;
• a wall that fixes the first electrode and the second electrode, constitutes a side wall of a bottomed concave component in which at least part of a bottom surface of the bottomed concave component is constituted by the first electrode and the second electrode, and has the outer lead component protruded therefrom;
• and
• a flange that protrudes outward from the wall on two sides of the outer lead component in plan view, a thickness of the flange being the same as a thickness of the outer lead component, wherein
• a height of the wall above an upper surface of the flange is greater than the thickness of the outer lead component.
