Abstract: Provided is a binder that has satisfactory storage stability and can express an excellent bonding strength for a glass fiber or powdered glass (impart a satisfactory strength to a bonded body with the glass fiber or the powdered glass). The binder of the present invention includes: a polymer having a hydroxyl group; and an ammonium salt of an inorganic acid, in which: the polymer contains a specific structural unit derived from a monomer represented by the general formula (1) and a specific structural unit derived from a monomer containing a carboxylic acid (salt) group.
