PROBLEM TO BE SOLVED: To provide a heat sink which improves the heat radiation efficiency of heat radiation fins, increases the convection flow speed of cooling air circulating between the heat radiation fins, and improves the cooling effect.SOLUTION: Multiple heat sink elements 10 are arranged in a queue. Each heat sink element 10 includes a first heat radiation fin 11 and a second heat radiation fin 12. The first heat radiation fin 11 includes: a first main heat radiation part 14; and a sub heat radiation part 15 supporting the first main heat radiation part 14. The second heat radiation fin 12 includes a second main heat radiation part 16 and has a surface shape different from that of the first heat radiation fin 11. The first main heat radiation part 14 is located at a position higher than the second main heat radiation part 16. The first heat radiation fin 11 and the second heat radiation fin 12 are arranged in a zigzag shape. |
