A hydrogen storage apparatus that includes multiple gas storage tanks that each house a storing/adsorbing material and through the interior of which a fluid travels is provided. The gas storage apparatus 10 includes roughly cylindrical gas storage tanks 20 that house hydrogen-storing alloy. The multiple gas storage tanks 20 are disposed longitudinally parallel to each other in an ordered fashion such that roughly triangular prism-shaped empty spaces are formed between multiple adjacent hydrogen storage tanks 20. Coolant paths through which coolant flows are formed in these roughly triangular prism-shaped empty spaces. These coolant paths are thermally connected to the hydrogen-storing alloy in the gas storage tanks 20 via constituent members of the gas storage tanks 20 and via heat transfer plates 28 disposed on the gas storage tanks 20.
