After plural semiconductor elements are stacked to form a stacked body P, side wirings are formed on the side surface of the stacked body P, thereby manufacturing a semiconductor apparatus in which the respective semiconductor elements are electrically connected to one another. In this case, as the semiconductor element, a semiconductor element 10 is employed in which a gold wire 16 with its one end connected to an electrode terminal of the semiconductor element is extended out to the side surface. A conductive paste 36 containing conductive particles applied over a predetermined length of a transferring wire 30 is transferred to the side surface of the stacked body P so that the gold wires 16 extended out to the side surfaces of the semiconductor elements 10, 10, 10 are connected, thereby forming the side wirings.

A substrate includes a storage portion which is defined by a base for mounting a light emitting element and a wall portion standing up on and from the base. A package is structured such that the upper end of the wall portion so formed as to surround the periphery of the storage portion is connected to a cover to thereby seal a light emitting element. A seal structure is composed of an uneven portion formed on the lower surface side surface of the base, a close contact layer formed on the surface of the uneven portion, a power supply layer formed on the close contact layer, and an electrode layer formed on the surface of the power supply layer. The uneven portion includes a first recessed portion formed at a position spaced in the radial direction from the outer periphery of a through electrode or from the inner wall of a through hole, and a second recessed portion formed at a position spaced further outwardly from the first recessed portion.

A plurality of quadrilateral-shaped semiconductor elements are stacked on the one surface of a circuit substrate. A side surface wiring for making electrical connection between each of the electrode terminals of the semiconductor elements and a pad formed on the circuit substrate is formed by applying a conductive paste containing conductive particles. A metal wire whose one end is connected to the electrode terminal is extended along a tapered surface formed by cutting off an edge of the electrode terminal surface on which the electrode terminal is formed among edges formed along each of the sides of the semiconductor element. At least a part of the metal wire extended from each of the electrode terminals of the semiconductor elements to the tapered surface is electrically connected to the side surface wiring.
