1. A method of manufacturing a connection structure, comprising:
a pasting step of pasting, from a film structure comprising a tape-shaped base material and a connection film formed on the tape-shaped base material, the connection film having a unit region of a predetermined length in the length direction of the tape-shaped base material and a predetermined width in the width direction of the tape-shaped base material to a first electronic component or a second electronic component having a plurality of terminal rows; and
a connecting step of connecting terminals of the first electronic component and terminals of the second electronic component through the connection film,
wherein the film structure includes, in the unit region, in addition to portions corresponding to the plurality of terminal rows, a non-pasting portion in which the connection film is not pasted,
wherein the first electronic component has a concave portion in a central portion of a mounting surface, and
wherein the film structure has the non-pasting portion in a direction from a peripheral edge portion of the unit region to a central portion of the unit region.
