Detecting device and measuring device

A detecting device, comprising:

• a first light-emitting unit that emits first light having a green wavelength band;
• a second light-emitting unit that emits second light having a wavelength band higher than the wavelength band of the green wavelength band;
• a first light-receiving unit that receives the first light emitted from the first light-emitting unit after propagating through a biological body;
• a second light-receiving unit that receives the second light emitted from the second light-emitting unit after propagating through the biological body;
• a detection surface that is configured to contact a surface of the biological body;
• a first light-shielding wall provided between (i) the first light-emitting unit and the second light-emitting unit and (ii) the first light-receiving unit, the first light-shielding wall being configured to block a part of the first light and the second light;
• and
• a bandpass filter provided at a light-receiving element of the first light-receiving unit, the bandpass filter being configured to selectively transmit the first light, wherein
• a distance from the first light-emitting unit to the first light-receiving unit is shorter than a distance from the second light-emitting unit to the second light-receiving unit, and
• a leading end portion of the first light-shielding wall protrudes from the detection surface.

• an angle-limiting filter provided at a light-receiving element of the first light-receiving unit, the angle-limiting filter being configured to limit an incidence angle of the first light reaching the first light-receiving unit, and
• a bandpass filter provided at the angle-limiting filter, the bandpass filter being configured to selectively transmit the first light, wherein
• a distance from the first light-emitting unit to the first light-receiving unit is shorter than a distance from the second light-emitting unit to the second light-receiving unit, the second light-receiving unit being devoid of an angle-limiting filter that limits an incidence angle of the second light reaching the second light-receiving unit and a bandpass filter that selectively transmits the second light, and
• a leading end portion of the first light-shielding wall protrudes from the detection surface.
