To provide a hydrogen sulfide gas adsorption structure that prevents time-dependent degradation of adsorption ability to hydrogen sulfide gas and is free from limitation of kinds of porous adsorbent, and to provide a battery pack having safety over a long period.SOLUTION: A hydrogen sulfide gas adsorption structure 1 is composed of an adsorbent 5 capable of adsorbing hydrogen sulfide gas and a packing medium 6 that has a gas permeability of polar molecules higher than that of nonpolar molecules and encloses the adsorbent airtightly. A battery pack accommodates the hydrogen sulfide gas adsorption structure together with a battery cell using a sulfide-based solid electrolyte in a battery case.SELECTED DRAWING: Figure 1 【課題】硫化水素ガスに対する吸着性能の経時的な劣化を防ぐとともに、多孔質吸着材の種類の制限がない硫化水素ガス吸着構造体、及び長期にわたり安全性を確保した電池パックを提供する。【解決手段】本発明に係る硫化水素ガス吸着構造体１は、硫化水素ガスを吸着可能な吸着材５が、非極性分子のガス透過率よりも極性分子のガス透過率が大きい包装材６で気密に包囲されて構成される。また、本発明に係る電池パックは、上記硫化水素ガス吸着構造体を、硫化物系固体電解質を用いた電池セルとともに電池ケースに収容して構成される。【選択図】図１
