PROBLEM TO BE SOLVED: To provide a water battery capable of generating an initial electricity by pushing at once, without injecting water from a water inlet.SOLUTION: A terminal 22 is constructed by a pressurizing part 20 positioned at the outside so as to separate from a terminal portion of a first side 11 of a negative cylindrical body 15; and a leg part 21 extending from the pressurizing part 20 and extending into an inside portion of the negative cylindrical body 15. The liquid storing portion 30 in which liquid is stored is arranged in the inside of the first side 11 of the negative cylindrical body 15. The liquid storing portion 30 includes: a first surface 31 of the first side 11 with elasticity; a second surface 32 positioned at the side opposite to the first surface 31; a supporting part 34 positioned at the first surface 31 and abutted to the leg part 21; and a needle part 35 sharp-pointedly extending from the supporting part 34 to the second surface 32 in the inside portion. By pressing the pressurizing part 20, the supporting part 34 is moved to the second side 12, the first surface 31 is elasticity deformed into a convex curve shape in a direction of the second side 12, and a tip portion of the needle part 35 pierces thorough the second surface 32. |
