a first member (I) containing a planar surface layer part and a protruding core part, and a second member (II) unified therewith,
the first member (I) being of a fiber-reinforced resin (A) formed mainly of a reinforcing fiber (a1) and a matrix resin (a2),
part of the threads of the reinforcing fiber (a1) extending penetratingly between the surface layer part and the core part,
the part of the threads of the reinforcing fiber (a1) extending penetratingly at a rate of 400 threads/mm 2 or more through the boundary surface between the surface layer part and the core part,
the reinforcing fiber (a1) having a number-average fiber length Ln of 1 mm or more, and
the core part forming a hollow structure. |
