PURPOSE: To obtain a synthetic resin molded article having a nauseating action for preventing him/her from choking if it is put in his/her mouth by a method wherein a communicating porous holding body with a nauseant held in its communicating pores is provided on the surface. CONSTITUTION: A synthetic resin molded article is formed by molding a synthetic resin material by a mold for extruding or injection molding. The synthetic resin material is prepared by loading and kneading a synthetic resin as a base with a communicating porous holding body. At this time, molding is conducted under the condition that the temperature of the mold is relatively low on the outer side thereof and relatively high on the inner side thereof, whereby a communicating porous holding body 4 can be exposed on an outer surface 3 of the molded article. A nauseant dissolved, for example, in a solvent is held in the communicating porous holding body 4 exposed on the outer surface 3 of the molded article. |
