An electricity storage module in which a plurality of battery cells are electrically connected via conductive members, wherein: each of the conductive members has a pair of electrode connecting parts that are welded to respective electrode terminals of a pair of adjacent battery cells, a base part that is connected to the pair of electrode connecting parts via a pair of elastically deformable parts, and a voltage detecting terminal that is connected to the base part and detects a terminal voltage of a battery cell.

Electricity storage module

An electrical storage module in which a plurality of electricity storage elements are electrically connected by conductive member, includes: a voltage detection board having voltage detection conductor that detects terminal voltage of the electricity storage element; a first external threaded component that connects the voltage detection conductor of the voltage detection board to the conductive member; and a cover that covers the voltage detection board; wherein: the cover is made from an insulating material; the conductive member has a first internal threaded portion into which the first external threaded component is to be screwingly engaged; and the distance between the inside surface of the cover that faces a head portion of the first external threaded component and an upper surface of the head portion of the first external threaded component is shorter than the distance between an end portion of the first internal threaded portion towards the cover side and an end of shaft portion of the first external threaded component.
