- the ESR was measured at ⁇ using an LCR meter (reactance-capacitance-resistance measuring device).
- Example 1 was able to lower ESR by about 20% compared to Comparative Example 1 using the conventional method. This is because the vaporization of the organic solvent in the conductive adhesive is promoted by making the vacuum state in the process of attaching the plate-like terminal to the element with the conductive adhesive, and the conductive in the conductive adhesive layer (10). This is probably because the density of the adhesive member has improved.

This is probably because many voids were generated inside as a result of promoting the vaporization of the organic solvent. On the other hand, in Example 2 in which pressure was applied by the pressing piece (55), the thickness of the conductive adhesive layer (10) was reduced to about one third of that at the time of application, and the ESR was reduced slightly.
