Abstract: An extraction bag with support includes a support member and a bag member which contains a material to be extracted or which is capable of containing a material to be extracted or which is capable of containing a material to be extraction, and is obtained by using a sheet composite on which the support member is arranged and joined along the center line of a water-permeable filtering sheet member, by folding the sheet composite into two and by passing it through a bag-making machine (and, as required, though a filling machine).
