Optical sensor and manufacturing method for the same

A method for manufacturing an optical sensor, the optical sensor including:

• a detecting part that has a plurality of detecting elements disposed on a semiconductor substrate and outputting intensities of light received as detection signals, and a light-shielding portion providing directional characteristics of light to the detecting elements such that the plurality of detecting elements indicate different intensities for a light received in a specified direction;
• and a signal processing part that receives the detection signals from the detecting part and processes the detection signals using an adjustment value that is set beforehand, the method comprising:
• obtaining information of an inclination angle of a window glass of a vehicle to which the detecting part is attached;
• selecting, from the plurality of detecting elements, a detecting element having a directional characteristic of light suitable for the inclination angle based on the information of the inclination angle;
• setting the adjustment value so as to coincide a signal value of a detection signal of the detecting element selected by the selecting, when the detecting part is irradiated with light in a predetermined direction in a state where the detecting part is inclined at the inclination angle, with a target value;
• and
• storing information of the detecting element selected by the selecting and the adjustment value set by the setting to the signal processing part.
