PROBLEM TO BE SOLVED: To provide an electrical connection structure of an electronic component to a flexible printed circuit board which easily electrically connects an electrode of the electronic component to a conductive pattern, and is capable of directly fixing the electronic component to the board without using a member for fixture and maintaining the electrical connection of the electrode of the electronic component to the conductive pattern even if a high pressure is iteratively and continuously acts.SOLUTION: In the electrical connection structure of the electronic component to the flexible printed circuit board, an electrode part 63 of an electronic component 60 is engaged to an electrode engage part 40 while being held between a front-side curved part 41 and a rear-side curved part 45. At least either a rear surface of the front-side curved part 41 or a front surface of the rear-side curved part 45 includes conductive patterns 221 and 231 which can be abutted to the electrode part 63 of the electronic component 60. The conductive pattern and the electrode part 63 are electrically connected by being directly abutted without interposing an electrical connection object such as a solder therebetween.SELECTED DRAWING: Figure 3 【課題】電子部品の電極を導電パターンに容易に電気的に接続すると共に、固定用部材を用いずに電子部品を基板に直接固定することができ、且つ、高い圧力が繰り返し作用し続けても、電子部品の電極の導電パターンへの電気的に接続を維持することができる、フレキシブルプリント基板への電子部品の電気的接続構造を提供すること。【解決手段】フレキシブルプリント基板への電子部品の電気的接続構造における、電子部品６０の電極部６３は、表側湾曲部４１と裏側湾曲部４５とに挟まれた状態で電極係合部４０に係合する。表側湾曲部４１の裏面、裏側湾曲部４５の表面のうちの少なくとも一方は、電子部品６０の電極部６３に当接可能な導電パターン２２１、２３１を有し、導電パターンと電極部６３とは、半田等の電気的接続物を介さずに直接当接することにより電気的に接続される。【選択図】図３
