Abstract:
A slider including a magnetic head part, an optical waveguide, and a near field element is fixed by first and second adhesives to a submount on which a semiconductor laser and a mirror are mounted, the mirror being placed at one end of the semiconductor laser in a resonance direction thereof and reflecting a laser in a direction intersecting with the resonance direction. At this time, at least parts of the first and second adhesives are applied to a position opposed to the semiconductor laser with an intermediation of the submount. The first adhesive having a higher Young's modulus than that of the second adhesive is applied onto an inflow end side of the slider including a solder connection portion, the second adhesive being applied onto an outflow end side of the slider.
