Beschreibung
Zusammenfassung:	A fusible plug for a high pressure gas cylinder includes a communication hole filled with a low melting point alloy, a porous metal sintered body is press-fitted in at least a part of the communication hole in a length direction, all or a part of the porous metal sintered body is impregnated with the low melting point alloy to solidify and composite the low melting point alloy. It is preferable that: the low melting point alloy has a melting point of 110° C.; the porous metal sintered body to be press-fitted is a porous metal sintered body having pores with an area ratio of 30% or more and 50% or less and having pores with a diameter exceeding 5 μm among the pores of 80% or more in terms of area ratio to all the pores; and the porous metal sintered body is a porous austenitic stainless steel sintered body.
