To obtain a bra cup totally realizing shape retention, fitness, elasticity, stretchability and air permeability in good balance.

This bra cup is constituted by piling a knitted fabric 2 on a resin foam sheet 1 of open cell type and bonding or joining the knitted fabric to the resin foam sheet. The bonding and joining positions of the resin foams sheet 1 and the knitted fabric 2 are distributed in a dotted state. Since using the resin foam sheet 1 of open cell type, the bra cup has excellent air permeability and better fitness to softly fit the bra cup to the skin. Since the resin foam sheet 1 of open cell type is combined with the knitted fabric 2, the bra cup has improved shape retention and maintains proper elasticity and stretchability in comparison with a case in which the sheet and the knitted fabric are separately used. Further since the resin foam sheet 1 is an open cell type and bonded or joined to the knitted fabric 2 in a dotted state, the bra cup can secure sufficient air permeability after combination.
