Thermal head, thermal printer, and manufacturing method for thermal head

A manufacturing method for a thermal head, comprising:

• forming a concave portion in a surface of a supporting substrate;
• laminating an adhesive layer made of an elastic material on a surface of a heat storage layer;
• bonding the heat storage layer in a laminated state with respect to the surface of the supporting substrate via the adhesive layer;
• and
• forming a plurality of heating resistors with spaces therebetween at a region corresponding to the surface of the heat storage layer, the region being opposed to the concave portion.
