Abstract

A terminal structure includes a wiring layer, a protective insulation layer, an open portion, and a connection terminal. The protective insulation layer covers the wiring layer. The open portion extends through the protective insulation layer in a thickness-wise direction to expose part of an upper surface of the wiring layer. The connection terminal is formed on the wiring layer exposed from the open portion. The open portion includes a wall surface, a depression, and a projection. The wall surface extends downward from an upper surface of the protective insulation layer. The depression is depressed into the protective insulation layer from the wall surface toward an outer side of the open portion. The projection is formed under the depression, continuously with the depression, and projected from the depression into the open portion further inward than the wall surface in a plan view. The depression is filled with the connection terminal.
