Claim:
1. A spin valve element comprising: a substrate; a spin injector made of a ferromagnetic material; a spin detector made of a ferromagnetic material; and a channel part made of a non-magnetic material, wherein the spin injector, the spin detector, and the channel part are formed on the substrate, the spin detector is arranged at a position separated from the spin injector in a direction parallel to a principal plane of the substrate, and are bonded to the channel part, the channel part is a linear member along a length dimension, is connected with the spin injector and the spin detector directly or through an insulating layer, and includes spin diffusion portions formed between bonding positions of the spin injector and of the spin detector, each spin diffusion portion extends outwardly in a width direction and is shaped asymmetrically with respect to a latitudinal axis as viewed from above.
