As a space is formed in the recessed part by retreating the occupying block 9, the primary resin 10 flows into the recessed part as it is drawn thereinto and being accompanied with it, the secondary resin 11 is also drawn into the recessed part and the primary resin 10 and the secondary resin 11 are filled in the recessed part.
