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.

DETAILED DESCRIPTION The foregoing first object is accomplished by a cylindrical type dry battery comprising: a first electrode member which has a first electrode terminal, and in which a cylindrical portion is formed by extending the first electrode terminal along the side surface; and a second electrode member having a second electrode terminal, the cylindrical portion being connected to the second electrode member through an insulating member close to the second electrode terminal, the outer periphery of the cylindrical portion being sheathed by a sheathing member, wherein a portion of the side surface of the sheath member is cut away so as to expose a portion of the cylindrical portion.
The foregoing second object is accomplished by a single-use camera of the present invention, for which a cylindrical type dry battery is used, characterized in that a contact strip for a positive electrode of the battery is provided which is contacted with a shoulder portion of the positive terminal in the cylindrical type dry battery with pressure.
When the battery is provided in the vertical direction, the height of the single-use camera is reduced.
