An object of the invention is to provide a food and drink conveying device that allows a travel body on which food and drink are placed to stably travel along a curved path of a travel path while maintaining the stability of the food and drink. A travel body (7) is provided with a travel body main unit (26), which is driven and conveyed, and a leading body (27) at the front end of the travel body main unit (26) in the direction in which the travel body (7) travels. The leading body (27) is supported by the travel body main unit (26) so as to be pivotable in a horizontal plane. Contact sections (29) are provided to both sides of the leading body (27) in the widthwise direction relative to the direction in which the travel body (7) travels and aligned on either side in the direction in which the travel body (7) travels. The contact sections (29) provided on the inner side of a curved path portion (10a) are configured to make contact in the curved path (10a) at two locations in a travel path (1a).

An all-solid-state cell has a fired solid electrolyte body, a first electrode layer integrally formed on one surface of the fired solid electrolyte body by mixing and firing an electrode active material and a solid electrolyte, and a second electrode layer integrally formed on the other surface of the fired solid electrolyte body by mixing and firing an electrode active material and a solid electrolyte. The first and the second electrode layers are formed by mixing and firing the electrode active material and the amorphous solid electrolyte, which satisfy the relation Ty>Tz (wherein Ty is a temperature at which the capacity of the electrode active material is lowered by reaction between the electrode active material and the solid electrolyte material, and Tz is a temperature at which the solid electrolyte material is shrunk by firing).

The present invention provides a secondary battery using a liquid electrolyte excellent in storage characteristics. The secondary battery includes a cathode, an anode, and a liquid electrolyte, where the cathode and the anode contain at least one mutual active material. This symmetrical electrode configuration, that the at least one active material for the cathode and the anode is mutual, enables equalization of an electrode electric potential difference before charge or after discharge; and thus electrolyte degradation is efficiently restrained to improve storage characteristics.
