Abstract: A magnetoresistance effect element includes a laminated body having a first ferromagnetic layer, a second ferromagnetic layer, and a nonmagnetic layer located between the first ferromagnetic layer and the second ferromagnetic layer, a first wiring connected to the laminated body, a sidewall insulating layer configured to cover at least a part of a side surface of the laminated body, a first electrode connected to a side of the laminated body opposite to the first wiring, and a second electrode and a third electrode provided on both sides of the laminated body with the sidewall insulating layer sandwiched therebetween, sandwiching the laminated body, and connected to the first wiring.

Abstract: Provided are benzotriazole derivative compounds of the general formula that are novel compounds capable of strongly absorbing light in the ultraviolet range, particularly 300-330 nm, while strongly absorbing light in the visible light short-wavelength range up to around 450 nm and being used suitably as a light absorber having high light fastness with a light-blocking function over an extended period of time. Preferably, R1 is a hydrogen atom or alkyl group, R2 is a C1-8 alkyl group, R3 is a hydrogen atom, alkyl group, acryloyloxyalkyl group, or methacryloyloxyalkyl group.
