Abstract
A thermal head includes a substrate, an electrode, a bonding material, an electrically conductive member, and a sealing material. The electrode is located on the substrate. The bonding material is located on the substrate or the electrode. The electrically conductive member is located on the bonding material and is electrically connected to the electrode via the bonding material. The sealing material is located on the substrate and covers the bonding material and the electrically conductive member. The bonding material includes a protruding portion located at an outer circumferential edge of the electrically conductive member away from the substrate and the electrically conductive member.
Claims7
A thermal head, comprising:
- a substrate;
- an electrode located on the substrate;
- a bonding material located on the substrate or the electrode;
- an electrically conductive member located on the bonding material and electrically connected to the electrode via the bonding material;
- and
