A sheet-shaped tissue adhesive/reinforcement includes a base sheet having biodegradability and a communicative porous structure, and an adhesive resin layer fixed and formed on the base sheet. The adhesive resin layer includes a first reactant made of an aldehyded glycan and a second reactant made of partially carboxylated polylysine, and has a molar ratio of 1 as a ratio of an aldehyde group of the first reactant to an amine group of the second reactant. The adhesive resin layer has a structure of granules derived from powder of the first reactant, and a connecting layer derived from the second reactant. The connecting layer connects the granules to each other and fixes each of the granules onto the base sheet, throughout the sheet-shaped tissue adhesive/reinforcement. |
