Abstract
An electrochemical device has a positive-electrode terminal, a negative-electrode terminal, a first electrode body, a second electrode body, and electrolytic solution. The positive-electrode terminal is flat plate-shaped, and has a first principal face and a second principal face on the opposite side. The negative-electrode terminal is flat plate-shaped, and has a third principal face and a fourth principal face on the opposite side. The first electrode body has a first wound positive-electrode non-forming region and a first wound negative-electrode non-forming region. The second electrode body has a second wound positive-electrode non-forming region and a second wound negative-electrode non-forming region. The first wound positive-electrode non-forming region, first wound negative-electrode non-forming region, second wound positive-electrode non-forming region, and second wound negative-electrode non-forming region are joined to the first principal face, third principal face, second principal face, and fourth principal face, respectively.
