Zusammenfassung:	PROBLEM TO BE SOLVED: To suppress growth (sintering) of metal particles under a high temperature environment; and to suppress poisoning of metal particles in the presence of a poisoning substance.SOLUTION: A zeolite including metal particles has a constitution described as follows (1)-(3). (1) The metal particles are included in a crystal of the zeolite having MFI structure. (2) A size of the metal particles is larger than a mean diameter of pores held by the zeolite. (3) A size of the zeolite is 50-1,000 nm.SELECTED DRAWING: Figure 1 【課題】高温環境下において、金属粒子の成長（シンタリング）を抑制すること。また、被毒物質の存在下において、金属粒子の被毒を抑制すること。【解決手段】次の（１）〜（３）の構成を有する、金属粒子を内包したゼオライト。（１）ＭＦＩ構造のゼオライトの結晶内に金属粒子が内包されている。（２）前記ゼオライトが有する細孔の平均径よりも、前記金属粒子のサイズの方が大きい。（３）前記ゼオライトのサイズが、５０〜１０００ｎｍである。【選択図】図１
