1. A fiber-reinforced resin article comprising:
a unidirectional fiber-reinforced resin sheet (UDS) and
a plurality of chopped sheets (CS) located on at least one face of the unidirectional fiber-reinforced resin sheet (UDS), wherein
the chopped sheets (CS) are small pieces of a unidirectional fiber-reinforced resin sheet that is the same as or differs from the unidirectional fiber-reinforced resin sheet (UDS),
the proportion of the chopped sheets (CS) relative to 100 parts by mass of the unidirectional fiber-reinforced resin sheet (UDS) is 40 parts by mass or more and 100 parts by mass or less, and
the chopped sheets (CS) comprise a chopped sheet that is disposed so as not to overlap any other chopped sheets.
