Summary:PURPOSE:To obtain an optical pickup capable of minimizing the unwanted radiation of a high frequency wave by making gaps to be hardly generated and enlarging fitting force. CONSTITUTION:This optical pickup is for reproducing information on an information recording medium and for recording information onto the information recording medium. The pickup has a shielding case made so as to enclose a high frequency wave generating source 104 by fitting a first member 30 with a second member 32 and the edge part of the first member 30 and the edge part of the second member 32 are formed to be uneven cross-sectional shapes.
