In order to provide an optical head in which the bonding strength between a flexure and itself is enhanced, the optical head (3) comprises a slider (32) for irradiating light emitted from a light source to a recording medium and an optical element (31) provided on the slider and used for guiding the light emitted from the light source to the slider. An adhesive pooling portion (31g) is provided on the upper surface (31a) of the optical element (31), and a tongue piece portion (46) is provided at an end of the flexure (44). The area of the adhesive pooling portion (31g) is larger than the area of a surface of the tongue piece portion (46), the surface being bonded to the optical element (31). The optical head (3) is bonded and fixed to the flexure (44) by coating an adhesive on the adhesive pooling portion (31g) and pressing the tongue piece portion (46) against the adhesive pooling portion (31g).
