Wound-type battery

A wound-type battery comprising:

• a wound electrode group that includes a first electrode and a second electrode having a polarity opposite to that of the first electrode;
• an electrolyte;
• a battery case that houses the electrode group and the electrolyte;
• a sealing plate that seals an opening of the battery case;
• an insulating plate that is disposed between the electrode group and the sealing plate and that has a hole;
• a first tab that passes through the hole to electrically connect the first electrode and the sealing plate to each other;
• and a second tab that electrically connects the second electrode and the battery case to each other,
• wherein at least a part of a region of the first tab that extends through the hole to a sealing plate side is covered with a tab tape on a side facing the insulating plate, and
• the tab tape includes at least a first adhesive layer on a first tab side and a second adhesive layer on a side opposite the first adhesive layer and is in contact with the first tab through the first adhesive layer.
