The invention includes a melt portion 40 that receives a stick-shaped hot melt adhesive 50, and heats, melts and injects the hot melt adhesive. The melt portion 40 is made from a metal. An inlet opening 80a to receive the stick-shaped hot melt adhesive 50 communicates with an outlet opening 83a to inject the liquid hot melt adhesive 50 via a plurality of passages 81b. The hot melt adhesive is heated and melted, and becomes the liquid hot melt adhesive. Because of this configuration, the contact area between the hot melt adhesive 50 and the melt portion 40 increases. Therefore, it is possible to efficiently heat and melt the hot melt adhesive 50 such that the temperature of the hot melt adhesive rises to a bonding temperature in a short time, and is injected. |
