Abstract
A dry battery includes a cylindrical housing, a first end plate and an electrode. The electrode protrudes from the first end plate and includes a tip end plate and a cylindrical side wall. The cylindrical housing, the first end plate, the tipe end plate and the cylindrical side wall each made of a conductive material are electically connected with each other so as to form a first conductive surface. A first contactor of an electrical power source circuit is arranged to come in contact with a part of the first conductive surface other than the tip end plate.
