PROBLEM TO BE SOLVED: To provide a fiber-reinforced plastic automobile hood panel capable of securely achieving desirable impact energy absorption caused by V-shaped bending deformation at the time of a collision accident. SOLUTION: In this fiber-reinforced plastic automobile hood panel, to a fiber-reinforced plastic outer 2 forming an outer surface, a fiber-reinforced plastic inner 3 for reinforcing the outer 2 is jointed. The inner 3 has a front reinforcement part 4 extending in the width direction in a vehicle body front part, a rear reinforcement part 5 extending in the width direction in a vehicle body rear part and side reinforcement parts 6 connecting the front reinforcement part 4 to the rear reinforcement part 5 so as to surround the outer periphery along the peripheral edge part of the outer 2. In portions on the side reinforcement parts 6 positioned within a range of 40 to 60% of a length from the front end of the front reinforcement part 4 and the rear end of the rear reinforcement part 5, inner bending introduction parts 9 with lower rigidity and/or lower strength than those of other portions are formed.
