Abstract
A signal transmitting/receiving device includes: a light source part configured to emit transmission light; a light-receiving part having a photodetector configured to receive reception light; and a condenser mirror configured to condense the reception light on the photodetector. The condenser mirror has a through hole configured to allow the transmission light emitted from the light source part to pass therethrough and align an optical axis of the light source part and an optical axis of the condenser mirror with each other. A reflection surface of the condenser mirror has a shape obtained by cutting out a columnar body extending in an emission direction of the transmission light, with a spheroid whose rotation axis is a major axis.
