PROBLEM TO BE SOLVED: To provide a two-core plastic optical fiber cable superior in the flexibility while keeping the necessary transmittability. SOLUTION: This optical fiber cable is manufactured by stranding up two plastic optical fiber codes 1 respectively formed by forming a coating 3 on a plastic optical fiber strand 2, and forming a sheath 5 outside the plastic optical fiber codes 1. On this occasion, a lay ratio defined by the formula. Where, P mm is a stranding pitch of two plastic optical fiber codes 1, 1, and D mm is a pitch diameter is within a range of 0.01%-1%.
