<p>A pickup device (5) is provided with a pickup body (51) as a case; a heat source (61) thermally connected to the pickup body; and an optical component (13), which is fixed to the pickup body by a plurality of fixing sections including at least two fixing sections (131, 132) which are at different distances from the heat source and belong to the pickup body. The pickup body is provided with at least one of slits (100, 101) having prescribed widths, in a direction of reducing a binding force (F) which is a factor of preventing at last one fixing section (132) of the two fixing sections from being displaced due to thermal expansion in accordance with the distance from the heat source.</p> |
