<P>PROBLEM TO BE SOLVED: To provide a light-emitting module whose photo detection element accurately detects light emitted from a predetermined light-emitting device even when the light-emitting device and the photo detection element are integrated. <P>SOLUTION: The light-emitting module having a light-emitting device disposed on a substrate is provided with: a photo detection element receiving light from the light-emitting device; and a light-shielding member formed around the photo detection element to surround the photo detection element. The light-shielding member is provided with an opening allowing the emitted light from the light-emitting device to pass through. When the light-emitting module is provided with a photo detection element receiving light from the light-emitting device, and a light-shielding member formed to surround the photo detection element and the light-emitting module, the light-shielding member is provided with an opening allowing the emitted light from the light-emitting device to pass to the outside of the light-emitting module. <P>COPYRIGHT: (C)2011,JPO&INPIT |
