Abstract
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.
