Propylene resin foam particles and foam particle molded article

An expanded propylene resin bead comprising a core layer being in a foamed state and constituted of a propylene-based resin composition (a) and a cover layer covering the core layer and constituted of an olefin-based resin (b),

• the propylene-based resin composition (a) satisfying the following (i) and (ii), and the olefin-based resin (b) satisfying the following (iii) or (iv):
• (i) the propylene-based resin composition (a) is a mixture of 65% by weight to 98% by weight of a propylene-based resin (a1) having a melting point of 145° C. to 165° C. and a flexural modulus of 1,200 MPa or more and 35% by weight to 2% by weight of a propylene-based resin (a2) having a melting point of 100° C. to 145° C. and a flexural modulus of 800 MPa to 1,200 MPa, provided that a sum total weight of the propylene-based resin (a1) and the propylene-based resin (a2) is 100% by weight;
• (ii) a difference between the melting point of the propylene-based resin (a1) and the melting point of the propylene-based resin (a2) [(melting point of a1)-(melting point of a2)] is 5° C. to 25° C.;
• (iii) the olefin-based resin (b) is a crystalline olefin-based resin having a melting point (TmB) that is lower than a melting point (TmA) of the propylene-based resin composition (a), with a difference between the melting point (TmA) and the melting point (TmB) [TmA-TmB] being more than 0° C. and 80° C. or less;
• and
• (iv) the olefin-based resin (b) is a non-crystalline olefin-based resin having a softening point (TsB) that is lower than the melting point (TmA) of the propylene-based resin composition (a), with a difference between the melting point (TmA) and the softening point (TsB) [TmA-TsB] being more than 0° C. and 100° C. or less.
