Zusammenfassung:	PROBLEM TO BE SOLVED: To provide an oxide removing filter capable of suppressing transmission of heat from molten metal to a core setting member when setting a core in low pressure casting.SOLUTION: An oxide removing filter 30 is set in a sprue part 14 of a casting apparatus for low pressure casting. The oxide removing filter 30 has a mesh-shaped filter part 32 and a heat shielding foil 34 covering the lower side of the filter part 32. The heat shielding foil 34 is dissolved in molten metal during casting. This makes it possible to suppress the heat from the molten metal from being transferred to a core setting member when setting the core in the low pressure casting.SELECTED DRAWING: Figure 2 【課題】低圧鋳造において中子を設置する際に溶湯からの熱が中子設置部材に伝達することを抑制することが可能な酸化物除去用フィルタを提供する。【解決手段】酸化物除去用フィルタ３０は、低圧鋳造用鋳造装置の湯口部１４に設置される。酸化物除去用フィルタ３０は、網状のフィルタ部３２と、フィルタ部３２の下側を覆う熱遮蔽箔３４とを有する。熱遮蔽箔３４は、鋳造時に溶湯に溶解される。これにより、低圧鋳造において中子を設置する際に、溶湯からの熱が中子設置部材に伝達することを抑制することが可能となる。【選択図】図２
