Compact optical unit

An optical scanning probe which is provided with a compact optical unit provided on a tip of the optical scanning probe, the compact optical unit comprising:

• a light emitting section for emitting a light;
• a first optical clement having a first reflecting section for reflecting a light which is emitted from the light emitting section;
• a second optical element having a second reflecting section which is disposed to face the first optical element;
• and
• a light condensing optical system for condensing the light,
• a second optical element supporting member for supporting the second optical element;
• a first spacer for supporting the light condensing optical system and the first optical element;
• a second spacer for supporting the first optical element and the second optical element supporting member;
• and
• a cover member for covering the outside of the first spacer and the outside of the second spacer,
• the first reflecting section and the second reflecting section are disposed so as to be diagonal to an optical axis of the light which is incident to the first reflecting section and the second reflecting section,
• a light transmitting section is disposed in the first optical element for transmitting the light which is reflected by the second reflecting section so as to be incident to the light condensing optical system,
• the second optical element is connected to a reference potential wiring which supplies a reference potential for the driving section which drives the second reflecting section and an X-axis driving signal wiring and a Y-axis driving signal wiring which supply the driving voltage to each axes, and
• the cover member is connected to the reference potential wiring,
• wherein the X-axis driving signal wiring and the Y-axis driving signal wiring are connected each other via the reference potential wiring and a resistance.
