Zusammenfassung:	The present invention provides a flat heat pipe with sectional differences and a method for manufacturing the same. The heat pipe has a flat hollow pipe body. A working fluid is sealed in the pipe body. The pipe body is provided along its length with a plurality of flat sectional difference portions having different widths. A connecting portion is formed between the sectional difference portions. The inner wall of the pipe body is formed with a plurality of grooves. The pitch between the grooves in the sectional difference portion of a relatively large width is larger than the pitch between the grooves in the sectional difference portion of a relatively small width.
