摘要

PROBLEM TO BE SOLVED: To provide an electric connection method and an electric connection structure which allow variations in height of an electric connection part of a flexible substrate to be absorbed and ensure the electric connection.

SOLUTION: This invention relates to an electric connection method for connecting a flexible substrate 60 on which a wiring pattern is formed with an electronic component 48. In an electric connection structure, the flexible substrate 60 is adhered to a support member 62 to be held so that a space 88 is provided on the side of contact parts of the flexible substrate 60 and the electronic component 48. The electric connection method includes: a filling process where a resin material 84 having low viscosity fills the space 88; a semi-cure process where the resin material 84 having the low viscosity is semi-cured; a pressing process where the support member 62 is contacted with the electronic component 48 to be pressed; and a cure process where the resin material 84 is fully cured.
