Abstract
According to a magnetic head and a method of manufacturing the same, a connecting process required when a magnetic head is attached to a head base can be implemented with ease. A pair of magnetic core half blocks (3, 4) are joined to form a magnetic core for forming a closed magnetic circuit. A thin film coil (6) is formed on the joint surface in which the magnetic core half blocks (3, 4) are joined. Terminals (7) of the thin film coil (6) are formed on the same plane of a head side surface (10a) intersecting the above-mentioned joint surface, resulting in a magnetic head (10) being constructed.
