PROBLEM TO BE SOLVED: To provide an embossed carrier tape suitable for recovery, a recovery system therefor and a bottom sheet constituent which have little degradation of quality performance even if a recycle material is used as a raw material. SOLUTION: The embossed carrier tape includes a material identifying means which shows that the bottom sheet is constituted of one of various types of resins. Preferably, the material identifying means is an identifying mark, a recycle mark or a laser mark printed with a stamper. The material identifying means sorts out and collects the respective embossed carrier tapes of which the bottom sheets are constituted of one of various resins from embossed carrier tape waste groups used for mounting. The second identifying means is capable of preventing the mixing of different materials. The available second classifying means is a gravity difference classifying method, a mechanical classifying method, and a near-infrared ray classifying method. COPYRIGHT: (C)2003,JPO
