    Abstract: PROBLEM TO BE SOLVED: To provide a manufacturing method of a printed wiring board capable of joining lands reliably, and to provide a manufacturing method of a printed circuit board unit. SOLUTION: A first support 33 is pressed toward a second support 28 according to the softening of an adhesive sheet 51. A filler 53b is reliably brought into contact between a conductive land 41 and a conductive land 31. After the adhesive sheet 51 is softened, the filler 53b is melted. Intermetallic compounds are formed between the filler 53b and the conductive lands 41, 31 and between the fillers 53b. In this manner, electric continuity is established between the conductive land 41 and the conductive land 31. After that, a matrix material 53a and the adhesive sheet 51 are cured. The first support 33 and the second support 28 are joined strongly. COPYRIGHT: (C)2010,JPO&INPIT
