1. A power storage module, comprising:
a flexible printed circuit board including a terminal,
wherein the flexible printed circuit board further includes:
an electrically conductive line,
a land that is electrically connected to the electrically conductive line and has a metal surface and is soldered to the terminal, and
a soldering restricting section that has a non-metal surface and is not soldered to the terminal,
wherein the terminal includes:
an overlapping section that overlaps the land and is soldered to the land and includes a removed section in a predefined area in the overlapping section, the removed section being formed in such a manner that a portion of the overlapping section is partially removed,
wherein the removed section is a through hole, and the predefined area is an inner area of the through hole,
wherein the through hole has an elongated circular shape including a small diameter section and a large diameter section that is larger than the small diameter section, and the soldering restricting section is an elongated circular area that is along a hole edge of the through hole, and
a protruding section that is continuous from the overlapping section and protrudes outside the overlapping section of the flexible printed circuit board, wherein
the soldering restricting section is in an area of the flexible printed circuit board that corresponds to the predefined area and does not overlap the overlapping section;
power storage elements including electrode portions that include positive electrode portions and negative electrode portions;
a connecting member connecting the electrode portions of the power storage elements that are adjacent to each other;
wherein the terminal is connected to the connecting member;
wherein the terminal connects the land of the flexible printed circuit board and the connecting member; and
wherein
the flexible printed circuit board extends to have a belt shape, and
the large diameter section of the through hole extends along an extending direction in which the flexible printed circuit board extends.
