PROBLEM TO BE SOLVED: To provide an optical pickup device capable of coping with the warp of an optical disk. SOLUTION: When four suspension wires 17A-17D are supported between a suspension base 12 and a lens holder 16 while coping with the warp of the optical disk D, values of at least one or more upper/lower spaces of wire supporting parts among total four upper/lower spaces of wire supporting parts formed by respective wire supporting parts ä(12a, 12c), (12b, 12d)}, (16a, 16c, etc.), arranged vertically at the outer peripheral side and the lower peripheral side of the suspension space 12 and the lens holder 16 are set to be different from the values of others, and also at least one wire among the four suspension wires 17A-17D using the same material is supported not in parallel with others.
