In a CPP element using a metal intermediate layer excellent in shot noise and response to high frequencies unlike a TMR element, its magnetoresistive effect film includes a magnetic layer mainly made of a half-metal exhibiting ferromagnetism, ferrimagnetism or antiferromagnetism, and largely variable in way of conduction in response to spin direction of electrons. Thereby, even when a region in the image data contains such high frequency components as a checkered pattern has, an image resistant to moir\xe9 that would be generated in magnifying or reducing of the image on a region basis can be displayed without deterioration of image quality. 7 or less, more preferably at least 0. The likelihood of a service request being made to the service may depend on the importance, ranking of the service request.
