| description | A crankshaft which has relatively high rigidity and in which induction hardening can be easily performed on a crank pin at low cost and an internal-combustion engine including the crankshaft are provided. A crankshaft 25 includes a first part 51 formed by integrally forming a first crank web 31 and a crank pin 33 and a second part 52 including a second crank web 32 in which a hole 37 in which the crank pin 33 is inserted is formed. The crank pin 33 includes a first pin portion 33a located inside the pin hole 37 of the second crank web 32 and a second pin portion 33b located outside the pin hole 37 of the second crank web 32. At least a portion of the first pin portion 33a and the second pin portion 33b include an induction hardening layer 61. |
