| 1. A magnetoresistive element comprising:
at least three metallic magnetic layers;
connection layers each provided between the metallic magnetic layers; and
electrodes which supply a current perpendicularly to a plane of a stack of the metallic magnetic layers and the connection
layers,
wherein a magnetization direction of a lowermost or uppermost metallic magnetic layer of the metallic magnetic layers is pinned,
and a magnetization alignment angle per connection layer is 30 to 60° at zero external field.
