A tubular lower mold partitioning wall is erected on a lower mold, and a three-dimensional mesh-like body is disposed with a part of a side face exposed with respect to the lower mold partitioning wall. When a pad main body is molded by foaming a liquid raw material, the mesh-like body is penetrated through the pad main body in a thickness direction. Since the mesh-like body is disposed with a part of the side face exposed with respect to the lower mold partitioning wall, the liquid raw material is hardened between the fibers on the side face of the mesh-like body, and the side face is attached to the pad main body. Therefore, it is possible that the mesh-like body is not easily displaced with respect to the pad main body while suppressing a sweaty feeling.

Method of manufacture of seat pad

A three-dimensional mesh-like body is disposed on a molding face of a lower mold onto which a liquid raw material of flexible foam is poured. An upper mold is laid over the lower mold to form a cavity, a projection projected on the upper mold toward the cavity is contacted with the three-dimensional mesh-like body, and the three-dimensional mesh-like body is fixed. The three-dimensional mesh-like body is attached and fixed to a front surface of a pad main body, so that the three-dimensional mesh-like body can be prevented from being displaced with respect to the pad main body. Moreover, the position of the three-dimensional mesh-like body can be prevented from being displaced in the process of foaming the liquid raw material because of the projection, and a vent hole can be formed on the pad main body. As a result, a sweaty feeling can be suppressed.

There is provided a seat padincluding a pad bodyformed of a foam resin molding and a breathable cushion bodyformed of a three-dimensional net structure made of linear bodies and provided in a pad surface side of the pad body. In the pad body, pulling-in groovesfor pulling in a skin materialare provided on a pad surface, wiresare embedded along the pulling-in grooves, and locking holesexposing part of the wiresare provided. The locking holesare provided so as to pierce the pad to a pad reverse side and the breathable cushion bodyis provided in a state where side surfaces thereof abut on the pulling-in groovesso as to communicate thereto.
