A wafer for a magnetic head includes a magnetic pole which has a design capable of avoiding pole missing due to processing with an improved resistance to the processing during a magnetic pole forming process. Each magnetic head element provided in the wafer has a recording magnetic pole film. The magnetic pole film has a large width part, a small width part and a support part. The small width part projects continuously from the large width part and extends with a constant width W, while the support part is continuous with an end of the small width part and has a width W. The width Wand the width Wsatisfy the relationship of 1&#x3c;W/W&#x3c;2.
