    • The present invention is a stratified scavenging two-cycle engine which has a more compact structure. The stratified scavenging two-cycle engine includes a scavenging flow passage (3) for connection between a cylinder chamber (4a) and a crank chamber (1a); and an air flow passage (2) connected to the scavenging flow passage (3), the scavenging flow passage (3) is continuously formed by a communication portion (30) extending from the crank chamber (1a) toward the cylinder chamber (4a) side; and a scavenging direction adjustment portion (31) extends from the communication portion (30) toward a cylinder inner surface (4b) side and opens at a scavenging port (3a) in the cylinder inner surface (4b). The air flow passage (2) extends into an area surrounded by the communication portion (30), the scavenging direction adjustment portion (31), and the cylinder inner surface (4b).
