    摘要: A base insulating layer is formed on a suspension body. Read wiring patterns, write wiring patterns and a ground pattern are formed in parallel on the base insulating layer. A first cover insulating layer is formed on the base insulating layer to cover the read wiring patterns, the write wiring patterns and the ground pattern. A ground layer is formed in a region on the first cover insulating layer above the write wiring patterns. A second cover insulating layer is formed on the first cover insulating layer to cover the ground layer.
