A fusible toy bead comprising a plurality of protrusions and a plurality of recesses, wherein each of the plurality of protrusions extends in a protruding direction and having a proximal end and a distal end in the protruding direction, and when viewed from any direction perpendicular to the protruding direction, the distal end has a width smaller than that of the proximal end,

• wherein each of the recesses is formed by connecting three surfaces opposed to each other such that a dihedral angle on an outer side of the fusible toy bead between each of the three surfaces and adjacent one of the three surfaces is not greater than 180 degrees.
