<p>In a metal-in-gap magnetic head, a pair of magnetic core halves made of ferrite are arranged to oppose to each other, and metallic magnetic films are applied to each of opposing surfaces of the pair of magnetic core halves. A hard glass layer and a chromium layer are applied to a gap plane of the magnetic head as a gap layer. A gap is formed so as to abut on the chromium layers between a pair of the gap layers. The hard glass layer includes borosilicate as a main component and it has Vickers hardness of the same as that of said metallic magnetic films or less and softening temperature of 550 DEG C or higher. Thus, a magnetic head does not generate a spacing loss when a tape slides thereon. <IMAGE></p>
