Abstract: A battery can has a cylindrical body section, an opening section at one end of the body section, and a bottom section closing the other end of the body section. An annularly grooved portion is formed by constriction near the open end of the opening section. The annularly grooved portion has an upper-groove section as the section closer to the open end than the narrowest section, which is positioned farthest inside, of the grooved portion, and also has a lower-groove section as the section closer to the bottom section than the narrowest section. The wall thickness T1 of the lower-groove section is larger than the wall thickness T2 of the body section.

Abstract: A wound-type battery includes a wound electrode group having a first electrode and a second electrode with polarity opposite to the first electrode, an electrolyte, a battery case, 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, and a first tab that passes through the hole to electrically connect the first electrode and the sealing plate to each other. 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. The tab tape includes at least a first adhesive layer 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.

Abstract: A projector device of the present disclosure includes a luminous tube made of quartz glass, a concave reflecting mirror in which the luminous tube is disposed, and an optical unit for projecting an image by utilizing light emitted from the concave reflecting mirror. The luminous tube has a luminous part, in which at least mercury is enclosed inside and a pair of electrodes is disposed so as to face each other, and a pair of sealing parts extending from the luminous part in opposite directions to each other. The luminous tube is disposed so as to direct the pair of electrodes in a vertical direction. A region of the image projected from the optical unit is a horizontally long rectangle.
