Beschreibung
Zusammenfassung:	A method for manufacturing a hollow protruding implement (1) including a fine hollow protrusion (3) having an opening (3h) of the present invention includes a protrusion forming step of inserting a projecting mold part (11) into a base material sheet (2A) from one face (2D) side thereof, the base material sheet containing a thermoplastic resin, thereby forming a non-penetrated hollow protrusion (3) projecting from another face (2U) side of the base material sheet (2A). Subsequently, an opening forming step is performed in which an opening (3h) that penetrates the hollow protrusion (3) is formed by using a contactless opening forming means disposed on the other face (2U) side of the base material sheet (2A).
