The present invention addresses the problem of providing a binder, a bound and shaped food, and a method for producing the bound and shaped food, and solves this problem by providing: a binder which contains, as active ingredients, pullulan, a branched α-glucan mixture having the characteristics (A) to (C), and an oligosaccharide, the contained amount of the pullulan per solid content of the binder being 10-50 mass%; a bound and shaped food obtained by binding and shaping by use of the binder; and a method for producing the bound and shaped food. (A) Glucose is used as a constituent sugar. (B) Included is a branched structure having a glucose polymerization degree of 1 or higher, the branched structure being linked, via a bond other than an α-1,4 bond, to a non-reduction terminal glucose residue positioned at one end of a linear glucan that is linked via α-1,4 bonds and that has a glucose polymerization degree of 3 or higher. (C) Isomaltose is produced, through isomaltodextranase digestion, in an amount of
