Connection module

A connection module that is attached, from a first direction, to a power storage element group formed by lining up a plurality of power storage elements each including an electrode terminal, the connection module comprising:

• a conductive member connected to the electrode terminal;
• and
• an insulation protector including a holding portion holding the conductive member,
• wherein the conductive member includes:
• a body portion made of a metal plate material in an approximately rectangular plate shape;
• and a projection portion projecting from one edge of the body portion in a direction intersecting with a plate surface of the body portion, and
• the holding portion includes a locking piece including:
• a first locking portion that restricts a movement of the conductive member in a direction orthogonal to the plate surface of the body portion;
• and a second locking portion that restricts a movement of the conductive member in a direction parallel to the plate surface of the body portion.
