BATTERY

To provide a battery capable of suppressing poor absorption of an electrolyte and suppressing leakage of the electrolyte.SOLUTION: A battery 1 includes a plate portion 12 including a positive electrode 21 and a negative electrode 22 having polarities different from each other, a battery case 11 containing an electrode plate portion 12 and provided with an opening, a lid portion 15 that closes the opening, and a liquid absorbing member 17 provided on the lid portion 15. The lid portion 15 includes a lid body 24 provided with a first exhaust hole 28, a control valve 25 that opens and closes the first exhaust hole 28 according to the internal pressure of the battery case 11, and an upper lid 26 that forms an accommodation space S that accommodates the control valve 25 between itself and the lid body 24 and that is provided with a second exhaust hole 29. The liquid absorbing member 17 is provided outside the accommodation space S so as to face the second exhaust hole 29.SELECTED DRAWING: Figure 4 【課題】電解液の吸収不良を抑制し、電解液の漏液を抑制可能な電池を提供する。【解決手段】電池１は、互いに異なる極性を有する正極２１及び負極２２を含む極板部１２と、極板部１２を収容すると共に、開口が設けられた電槽１１と、開口を塞ぐ蓋部１５と、蓋部１５上に設けられた吸液部材１７と、を備える。蓋部１５は、第一排気孔２８が設けられた蓋本体２４と、電槽１１の内部圧力に応じて第一排気孔２８を開閉する制御弁２５と、蓋本体２４との間に制御弁２５を収容する収容空間Ｓを形成すると共に、第二排気孔２９が設けられた上蓋２６と、を有する。吸液部材１７は、第二排気孔２９と対向するように収容空間Ｓの外部に設けられている。【選択図】図４
