The resin formed panel comprises: a base plate constituted from a fiber reinforced resin containing a continuous fiber and a thermoplastic resin, wherein a recessed portion recessing from the plate surface has been formed; and an attachment member constituted from a thermoplastic resin, and inserted into the recessed portion while being fused to the bottom surface and inner wall surfaces of the recessed portion. This constitution allows a resin formed panel and an access door panel to be provided, which allow strength to be maintained more stably.
