A linear active cell region is formed from a plurality of divided active cell regions arranged apart from each other in a second direction (y direction). The linear hole collector cell region is formed from a plurality of divided hole collector cell regions arranged apart from each other in the second direction (y direction). A P-type floating region is formed in a semiconductor substrate between the linear active cell region and the linear hole collector cell region adjacent to each other in a first direction (x direction), between the divided active cell regions adjacent to each other in the second direction (y direction), and between the divided hole collector cell regions adjacent to each other in the second direction (y direction).
