PROBLEM TO BE SOLVED: To provide a configuration capable of suppressing an electromagnetic wave generated around a positive electrode connection terminal and a negative electrode connection terminal in a wound-type battery having an electrode body formed by being wound in a state where a positive electrode and a negative electrode formed in a belt-shape, respectively and a separator are overlapped on each other.SOLUTION: A wound-type battery includes: an electrode body (30) formed in a pillar shape extending in an axis line direction by being wound in a state where a positive electrode (31), a negative electrode (32) and a separator (33) are overlapped on each other; a positive electrode lead (34) which is electrically connected to the positive electrode (31) and functions as a positive electrode terminal of the electrode body (30); and a negative electrode lead (35) which is electrically connected to the negative electrode (32) and functions as a negative electrode terminal of the electrode body (30). The positive electrode lead (34) and the negative electrode lead (35) are mounted on the electrode body (30) so as to be located on one side with respect to an axis line when the electrode body (30) is viewed from the axis line direction and overlapped with each other when the electrode body (30) is viewed from the side surface. |
