PROBLEM TO BE SOLVED: To provide an optical head insusceptible to variation of outer atmosphere by dripping an bonding agent at a position opposite to the pressing direction of a leaf spring. SOLUTION: A detection lens 7 or a conversion lens is secured by means of a leaf spring 12 abutting against the bottom face of an optical base and the side fixing face to press the lens under positioned state, and a bonding 15 filling the gap at a position opposite to the pressing direction of the leaf spring 12. A groove 14 for dripping the bond is made between the bottom and side faces of the optical base and the detection lens 7 or the conversion lens. |
