Summary:To provide a seal structure for a battery case capable of improving the sealability between a fiber-reinforced resin layer of a case member and a sealing member.SOLUTION: Provided is a seal structure for a battery case that houses a plurality of batteries. The seal structure for the battery case comprises: a lower case member and an upper case member that configure the battery case; and a sealing member provided between the members at a bonding portion between their peripheral parts. At least one of the lower and upper case members has a fiber-reinforced resin layer on the sealing member side surface at the bonding portion. The fiber-reinforced resin layer has a resin coating layer on a surface at the sealing member side.SELECTED DRAWING: Figure 3 【課題】ケース部材の繊維強化樹脂層とシール部材との間のシール性を向上し得るバッテリーケースのシール構造を提供する。【解決手段】バッテリーケースのシール構造は、複数のバッテリーを収納したバッテリーケースのシール構造である。バッテリーケースのシール構造は、バッテリーケースを構成するロアケース部材及びアッパケース部材と、それら部材の周縁部同士の接合部位においてそれら部材の間に設けられたシール部材を備える。ロアケース部材及びアッパケース部材のうちの少なくとも一方のケース部材が、接合部位におけるシール部材側の表面に繊維強化樹脂層を有する。繊維強化樹脂層が、シール部材側の表面に樹脂被覆層を有する。【選択図】図3
