Foam molded body and food storage tray

The invention relates to a foam molded body and a food storage tray. Provided is a foam molded body that does not contain an antibacterial component and can exhibit antibacterial properties. A foam molded body which is molded from polylactic acid and in which the value of the interface expansion area ratio (Sdr), which is a composite parameter of three-dimensional surface properties, measured from the surface of a contact surface that comes into contact with a food is within the range of 20-200%. A plurality of accommodating recesses (11) are formed in the fruit and vegetable accommodating tray (1) formed from a foam molded body made of polylactic acid, the inner side surfaces (11a) of the accommodating recesses (11) are formed in a hemispherical shape, and fruits and vegetables as food are accommodated in the accommodating recesses (11). The value of Sdr of the fruit and vegetable accommodating tray (1) formed by the foam molding body is in the range of 20-200%, and more boundaries in contact with fruits and
