PROBLEM TO BE SOLVED: To provide a magnetic head which has high saturation magnetic flux density and which can generate a sufficient magnetic field corresponding to high recording density. SOLUTION: At least either of a lower part magnetic core and an upper part magnetic core has a magnetic pole layer of saturation magnetic flux density of 23,000 gauss or more consisting of a magnetic film including elements of two kinds or more out of Co, Ni, and Fe prepared by an electroplating method in a range of a plating bath of pH2 or less.
