Semiconductor storage device

A semiconductor storage device comprising:

• a first board including a first surface and a second surface, the second surface being on a side of the first board opposite to the first surface thereof;
• a molded resin covering the first surface as viewed in a thickness direction of the first board;
• and
• a memory chip provided between the first surface and the molded resin,
• wherein:
• the first board includes a terminal, the terminal being provided on the second surface, and the terminal being exposed to outside,
• the terminal includes a first non-planar portion provided on an outer surface of the terminal,
• the first non-planar portion includes at least one of a plurality of recesses and a plurality of protrusions,
• the first non-planar portion includes a first recessed portion and a first protruding portion, and
• the first recessed portion and the first protruding portion are aligned alternately on the first non-planar portion.
