PROBLEM TO BE SOLVED: To provide a center pillar structure made of fiber-reinforced resin which can achieve shock absorption load equal to a metal center pillar at a side collision.SOLUTION: A center pillar structure made of fiber-reinforced resin includes: an outer member 30 which is made of the fiber-reinforced resin and is arranged on an outer side of a vehicle width direction; an inner member 20 which is made of the fiber-reinforced resin, is arranged on an inner side of the vehicle width direction, and is joined to the outer member; and an energy absorption member 50 which is made of the fiber-reinforced resin and is arranged between the outer member and the inner member. The energy absorption member includes a plurality of energy absorption plates 51, 52, 53, and 54 which extend in the vehicle width direction and are arranged and overlapped in a height direction of a vehicle body, and an outer side thickness in the vehicle width direction of at least one energy absorption plate is smaller than a thickness of an inside in the vehicle width direction.SELECTED DRAWING: Figure 5
