Terminal cooling part for electricity storage device, bus bar for electricity storage device, and electricity storage device module

A bus bar for an electricity storage device, the bus bar comprising:

• a pair of terminal cooling parts;
• and
• a pipe formed of metal,
• wherein
• each of the pair of terminal cooling parts includes
• a first plate that is formed of metal, is superimposed on an end surface of an electrode terminal of the electricity storage device, and includes a joining portion that is joined to the electrode terminal, and
• a second plate that is formed of metal, is opposed to a surface of the first plate at an opposite side to a surface of the first plate that is superimposed on the end surface of the electrode terminal except for the joining portion, includes a raised portion that forms a refrigerant circulating space between the raised portion and the first plate, and is configured such that a portion around the raised portion is joined to the first plate, and
• the second plate includes
• a supply port via which a refrigerant is supplied to the refrigerant circulating space, and
• a discharge port via which the refrigerant is discharged from the refrigerant circulating space, and
• the pipe connects the discharge port of one terminal cooling part of the pair of terminal cooling parts and the supply port of the other terminal cooling part of the pair of terminal cooling parts to each other.
