Liquid droplet ejecting head, printing apparatus and method of manufacturing liquid droplet ejecting head

摘要

A liquid droplet ejecting head includes: a base substrate that has a concave portion that is formed to be open toward an upper surface and a wiring pattern; and an IC package that is electrically connected to the wiring pattern. The concave portion has a bottom portion and a pair of first side wall portions which stand obliquely on the bottom portion so as to be opposed to each other. Further, the wiring pattern has a plurality of linear objects, each of which is continuous and is constituted of a first part, a second part, and a third part. In addition, the IC package is formed in a chip shape, has a plurality of terminals which are formed on a front side surface, and is disposed such that the front side surface faces the concave portion, and each terminal is electrically connected to the first part.
