POWER STORAGE DEVICE AND METHOD OF MANUFACTURING SAME

A method of manufacturing a power storage device includes: inserting an electrode assembly into a case main body; and after inserting the electrode assembly into the case main body, joining a first conductive member and a second conductive member, the first conductive member being electrically connected to a first electrode through a first electrode tab, wherein at least before joining the first conductive member and the second conductive member, at least one of the first conductive member and the second conductive member has a projection, and the joining the first conductive member and the second conductive member includes applying an energy ray to the projection so as to join the first conductive member and the second conductive member.
