An assembled battery includes: a plurality of batteries; a holder having a holder part configured to hold outer circumferential surfaces of the batteries inserted in the battery through-holes; and a plurality of adhesive bodies that combine the batteries and inner circumferential surfaces of the holder part with each other. Each of the inner circumferential surfaces includes: a posture restricting portion configured to restrict a posture of each battery; a departing portion configured to depart from each battery around the whole circumference of the battery even when the battery takes any posture within the range; and a liquid-pouring groove connected from the second surface to the departing portion, and every adhesive body includes a whole-circumferential combined portion where the departing portion and the departing-portion opposing portion of each battery are combined with each other around the whole circumference.
