ている。The resin composition 3 is supplied from a nozzle with a predetermined diameter attached to the tip 7.
is discharged to apply the required amount onto the coating surface. However, with this structure, the amount of discharge from the nozzle attached to the tip 7 is not constant due to the friction of the contact part 5 between the rubber piston 4 and the inner wall of the cylinder part 1, resulting in variations in the adhesive strength after bonding the adherend. This may be caused by the resin composition 3 creeping up on the surface of the adherend or adhesion to the electrode on the surface of 1 due to the amount of the discharged resin composition being too large when placing the adherend on the discharged resin composition and adhering it. Problems include contamination of adherends and poor conductivity.

無く、加圧時間の長さに応じた吐出量が得られない。Table 1 Comparison of Yield (Unit: wt%) In Examples and Comparative Example 1, silver paste was applied with the piston attached. As a result, as shown in Figure 6,
In B (Comparative Example 1), the silver paste was not discharged when the pressurization time was 0.1 seconds or less, and there was no proportional relationship between the pressurization time and the discharge amount, and the discharge amount was obtained according to the length of the pressurization time. I can't do it.

。On the other hand, a person (example) can discharge even if the pressurization time is 0.1 seconds or less, and can obtain a discharge amount corresponding to the length of the pressurization time. Further, when the pressurization time of A (Example) is the same as that of C (Comparative Example 2) and the discharge amount is compared, the discharge amount of A (Example) is larger. This requires less pressurization than C (comparative example 2) when a fixed amount is discharged, that is, the discharge is faster.

観察でき、銀ペーストの残存量が一目でわかる。As shown in Table 1, in Comparative Example 2, 80 pieces of silver beneto were discharged, but the remaining 20% adhered to the inner wall of the cylinder. Since the silver paste attached to the inner wall is opaque, the remaining amount of silver paste cannot be seen during the intermediate stage. However, in the example, 98% of the silver paste was discharged with almost no adhesion to the inner wall of the cylinder, so the inside of the cylinder could be clearly observed and the remaining amount of silver paste could be seen at a glance.
