The invention belongs to the sensor technology field and especially relates to a flexible pressure sensor and a manufacturing method. The flexible pressure sensor comprises a first flexible substrate,a first flexible conducting layer, a second flexible conducting layer and a second flexible substrate which are successively stacked. The first flexible conducting layer comprises first embossment arrays which are arranged periodically. The second flexible conducting layer comprises second embossment arrays which are arranged periodically. The first embossment arrays and the second embossment arrays are arranged adjacently. The first flexible conducting layer and the second flexible conducting layer contain a conductive composite material. The flexible pressure sensor possesses characteristics of high sensitivity, rapid response time and good stability.
