Fuse unit and conductive module

A conductive module comprising:

• a connection conductor electrically connected to an electrode terminal of a battery cell constituting a battery module;
• and
• a fuse unit that electrically connects the connection conductor to a battery monitoring unit that monitors a battery state of the battery cell, wherein
• the fuse unit includes
• a chip fuse that fuses a fusible portion when an overcurrent flows between the connection conductor and the battery monitoring unit,
• a first terminal fitting including a first electrical connection portion electrically connected to a first electrode of the chip fuse and electrically connected to the connection conductor,
• a second terminal fitting including a second electrical connection portion electrically connected to a second electrode of the chip fuse and electrically connected to the battery monitoring unit, and
• an extendable shape portion provided at at least one of the first terminal fitting and the second terminal fitting, the extendable shape portion enabling the at least one of the first terminal fitting and the second terminal fitting to extend and contract along an alignment direction of the first terminal fitting and the second terminal fitting.
