Thermal head and thermal printer

A thermal head comprising:

• a substrate;
• a plurality of heat generating portions disposed on the substrate;
• a common electrode disposed on the substrate and electrically connected to the plurality of heat generating portions;
• a plurality of individual electrodes disposed on the substrate and each electrically connected to a corresponding one of the plurality of heat generating portions;
• a first insulation layer disposed on the heat generating portions, the common electrode, and the individual electrodes;
• a second insulation layer located adjacent to the first insulation layer and disposed on the individual electrodes;
• a static removing layer that is grounded;
• a first stacked portion in which the second insulation layer, the first insulation layer, and the static removing layer are stacked in this order;
• and
• a covering layer covering the first stacked portion,
• wherein an inclination angle between a side surface of the covering layer closer to the heat generating portions and the substrate is greater than an inclination angle between a side surface of the covering layer farther from the heat generating portions and the substrate in a sectional view.
