摘要：
In an optical position detection device, when emitting the detection light from the light source section, the light receiving section receives the reflected light from the target object with the first light receiving element and the second light receiving element. The first light receiving element and the second light receiving element are arranged to have the intersection angle greater than 90° and smaller than 180°, the intersection angle being formed between the normal direction with respect to the light receiving surface of the first light receiving element and the normal direction with respect to the light receiving surface of the second light receiving element.
