A method of manufacturing a package,
- the package comprising:
- a rectangular floor portion comprising two long sides, which are in opposite position to each other, and two short sides, which are in opposite position to each other, a first short side surface and a second short side surface arranged on respective portions of the two short sides of the rectangular floor portion, and a first long side surface and a second long side surface arranged on respective portions of the two long sides of the rectangular floor portion;
- a plurality of high-frequency internal terminals arrayed in an internal terminal portion on an inner side of the first short side surface, the high-frequency internal terminals connected to a high-frequency optical device mounted inside the package;
- a plurality of high-frequency external terminals arrayed in a first external terminal portion on an outer side of the rectangular floor portion and on an outer side of the first short side surface, the high-frequency external terminals connected to the high-frequency internal terminals and connected to lead pins;
- and
- a plurality of DC electrode terminals arrayed in a second external terminal portion on an outer side of the first long side surface,
- the method comprising:
- producing a first frame having an “L” shape in a planar view and comprising portions of the first short side surface and the first long side surface, a part of the second long side surface, and the internal terminal portion, the first frame including conductor layers and insulating layers, the conductor layers and the insulating layers being stacked alternately, the conductor layers being connected to the plurality of DC electrode terminals, a length of the portion of the first long side surface in a first direction parallel to a longitudinal direction of the first long side surface being longer than a length of the internal terminal portion in the first direction, and a length of the part of the second long side surface in the first direction being substantially the same as the length of the internal terminal portion in the first direction;
- producing a second frame having an “L” shape in the planar view and comprising portions of the second short side surface and the second long side surface;
- producing a plate-shaped base material serving as the rectangular floor portion;
- and
- combining the first frame, the second frame, and the plate-shaped base material to form the package.
