Abstract: This optical detection device includes a first photoelectric conversion element that outputs a first output, and a second photoelectric conversion element that outputs a second output, and is configured to combine a first signal caused by the first output with a second signal caused by the second output, in a state where a first condition and a second condition are satisfied. The first condition is a condition that an absolute value of an amount of change until the first signal reaches a peak is different from an absolute value of an amount of change until the second signal reaches a peak, and the second condition is a condition that a sign of the amount of change until the first signal reaches the peak is different from a sign of the amount of change until the second signal reaches the peak.

Abstract: A magnetoresistive effect device includes a first magnetoresistive effect element, a second magnetoresistive effect element, a first port, a second port, a signal line, and a direct-current input terminal. The first port, the first magnetoresistive effect element, and the second port are connected in series to each other in this order via the signal line. The second magnetoresistive effect element is connected to the signal line in parallel with the second port. The first magnetoresistive effect element and the second magnetoresistive effect element are formed so that the relationship between the direction of direct current that is input from the direct-current input terminal and that flows through the first magnetoresistive effect element and the order of arrangement of a magnetization fixed layer, a spacer layer, and a magnetization free layer in the first magnetoresistive effect element is opposite to the above relationship in the second magnetoresistive effect element.
