PROBLEM TO BE SOLVED: To provide a beverage extraction package that enables simple unsealing with no outflow of content and an efficient extraction of a full-bodied extract with a high flavor containing content-intrinsic ingredients.SOLUTION: A beverage extraction package 10A comprises one side unsealing line 23 attached in a part inside of a seal portion 21a formed along a top side part 20a parallel with a fold overlapping direction ZY of nonwoven fabric 20 of a bag body 11 and one side unsealing line 22 attached in a part inside of a seal portion 21c formed along a top side part 20c orthogonal to the top side part 20a and a bottom side part 20b. Alternatively, the package comprises an arc-like unsealing line where a folding side part 20d and the bottom side part 20b are attached in an arc form centered on an orthogonal corner part to combine one end side attachment part of the folding side part 20d with the other side attachment part of the bottom side part 20b.
