Optical disk apparatus and optical pickup

An optical disk apparatus comprising:

• a light source for emitting a light flux;
• a light source drive circuit for causing the light source to emit the light flux;
• an optical base having an optical system disposed thereon, the optical system comprising an objective lens for guiding the light flux emitted from the light source to a disk-shaped recording medium;
• a moving mechanism for moving the optical base;
• a first heat radiation member connected to the light source;
• and
• a second heat radiation member connected to the light source drive circuit and being different from the first heat radiation member,
• wherein the first heat radiation member and the second heat radiation member are provided so as to face the disk-shaped recording medium, and
• wherein the second heat radiation member is disposed on the disk-shaped recording medium side with respect to the first heat radiation member, and the second heat radiation member has a hole provided therein, for exposing the first heat radiation member to the disk-shaped recording medium.
