Claim 0:
1. A molding apparatus comprising a nozzle, a guide member guiding a molding material to the nozzle, and a heating device, wherein
the molding material contains a thermoplastic resin,
the guide member being a tubular member,
a prevention structure to prevent melting of the molding material during transportation of the molding material through the guide member is a heat insulation material, or a gap between the heating device and the guide member,
a part of the guide member is disposed inside the nozzle,
the heating device heats the molding material so as to melt during transportation of the molding material through a nozzle port of the nozzle,
the nozzle includes the nozzle port and a hole that is communicated with the nozzle port,
a tip end side of the guide member is disposed toward the nozzle port,
the shortest distance between a location of the nozzle port and the tip end position of the guide member is smaller than an inner diameter of the nozzle port,
a temperature of the guide member is less than a temperature at which the molding material being transported through the guide member melts and is 50° C. or less,
the heat of the heating device does not melt the molding material during transportation of the molding material through the guide member, and
the nozzle port has a rounded shape.
