<p>Provided are an electric storage device provided with a current collecting member capable of increasing the strength of connection with an electrode assembly, and a method for manufacturing the current collecting member. A current collecting member 6 includes a first portion 600 electrically connected to an external terminal 4, and a second portion 601 extending out of a second end portion of the first portion 600 and electrically connected to an electrode assembly 2. The second portion 601 includes a base portion 601a the first end portion of which is connected to the second end portion of the first portion 600, a twisted portion 601 d the first end portion of which is connected to the second end portion of the base portion 601a, and an insertion portion 601f the first end portion of which is connected to the second end portion of the twisted portion 601d and which is inserted into a winding center of the electrode assembly 2, so as to be electrically connected to the electrode assembly 2. The second portion 601 preferably further includes a reverse-twisted portion 601d' which is twisted in a direction opposite to the twisting direction of the twisted portion 601d and the first end portion of which is connected to the second end portion of the insertion portion 601f, and a leading end portion 60h the first end portion of which is connected to the second end portion of the reverse-twisted portions 601d'.</p> |
