Fixing structure of conductor unit

A fixing structure of a conductor unit comprising:

• a connection conductor that is connected directly or indirectly with at least one electrode terminal in an electrode terminal group of a plurality of battery cells arranged in a same direction;
• a linear conductor connected with a battery monitoring unit configured to monitor the battery conditions of the battery cells;
• a fusible body that is connected between the connection conductor and the linear conductor, the fusible body being configured to fuse when an overcurrent flows between the connection conductor and the linear conductor;
• and
• an insulative resin-molded member that contains the fusible body inside the insulative resin-molded member, wherein
• the connection conductor includes holding portions that are disposed inside the resin-molded member and hold the resin-molded member,
• the holding portions are formed in at least two places spaced apart from each other,
• the holding portion is formed in a plate-like shape, and provided with at least one through hole, and
• a part of the resin-molded member is disposed inside the through hole.
