Thermal print head

A thermal print head, comprising:

• a substrate including a main surface;
• an insulating film arranged on the main surface;
• a first wiring layer arranged on the insulating film;
• a first interlayer insulating film arranged on the first wiring layer;
• a heat-generating body film;
• and
• a second wiring layer arranged on the first interlayer insulating film with the heat-generating body film interposed therebetween,
• wherein a bump is formed on the main surface,
• wherein the bump extends along a first direction in a plan view,
• wherein the second wiring layer extends along a second direction orthogonal to the first direction so as to intersect the bump in a plan view, and includes a first wiring, a second wiring, a third wiring, and a fourth wiring arranged along the first direction,
• wherein the second wiring is located between the first wiring and the third wiring,
• wherein the third wiring is located between the second wiring and the fourth wiring,
• wherein one end of the first wiring in the second direction is connected to one end of the second wiring in the second direction,
• wherein one end of the third wiring in the second direction is connected to one end of the fourth wiring in the second direction,
• wherein the other end of the second wiring in the second direction and the other end of the fourth wiring in the second direction are electrically connected to the first wiring layer, and
• wherein the first wiring, the second wiring, the third wiring, and the fourth wiring are partially removed such that the heat-generating body film is exposed at a position overlapping with the bump in a plan view.
