Thermal printer head and manufacturing method thereof

A thermal printer head, comprising:

• a first substrate, having a first main surface expanded in a first direction and a second direction intersecting the first direction, a first inclined surface located on one side of the first direction relative to the first main surface and inclined relative to the first main surface in a manner of being distant from the first main surface and facing an opposite direction as the first main surface, and a second inclined surface located on another side of the first direction relative to the first main surface and inclined relative to the first main surface in a manner of being distant from the first main surface and facing an opposite direction as the first main surface;
• an electrode layer, laminated on the first main surface, the first inclined surface, and the second inclined surface;
• a resistor layer, having a plurality of heat dissipation portions respectively laminated on the first inclined surface and crossing separated parts in the electrode layer;
• a driving integrated circuit (IC), for controlling the current passing through each heat dissipation portion;
• and
• a plurality of wires, respectively joined to the driving IC and joined to the second inclined surface through the electrode layer.
