Abstract
For forming bores for insertion of optical fibers, etc., on one side surface of a micro lens with high accuracy and easy work, a laser processing method that includes the steps of: irradiating a laser beam onto the one side surface of the micro lens; then focusing the laser beam in a layer having superiority in absorbency with respect to the laser beam; and forming the bores because the laser beam exceeds the threshold value of causing fusion, evaporation or ablation in the superior laser beam absorption layer.
