CARRIER FILM-ATTACHED ELECTROLYTE COPPER FOIL, METHOD FOR MANUFACTURING THE SAME, AND COPPER FOIL LAMINATES OBTAINED BY USING THE SAME

摘要

PURPOSE: A carrier foil attached electrolysis copper foil, a manufacturing method thereof, and a copper foil laminate obtained by the carrier foil attached electrolysis copper foil are provided to have a low and stable peeling degree of a carrier foil. CONSTITUTION: When a depth direction profile of a heat resisting metal component is measured forward the carrier foil side using a GDS analysis device in an electrolysis copper foil layer side of a corresponding normal carrier foil attached electrolysis copper foil(1), a half value width of a peak is W1. When a depth direction profile of a heat resisting metal component is measured forward the electrolysis copper foil layer side after heating the carrier foil attached electrolysis copper foil at 300°C for 120 minutes under the air, a half value width of a peak is W2. The relation of ([W2] - [W1]) / [W1] <= 0.3 is satisfied.
