Is it infringement to use characters to make logo?

As long as the cartoon character you value constitutes an independent work and the work is still within the scope of copyright protection, your unauthorized use constitutes infringement. Even if you declare that the copyright of the work belongs to the original author, you still only solve the problem of the right of signature, not the right to use and other rights, so it still constitutes infringement.
