The invention relates to a sheet-shaped electronic component, comprising an electronic component main body and an insulation terminal plate. The electronic component main body comprises a functional element and a pair of leads, and the insulation terminal plate comprises an insulative main portion and an auxiliary terminal made of metal. The main body portion is provided with a first through hole, a groove which is communicated with the first through hole and is formed in a direction vertical to the first through hole, a concave portion formed at the same side of the groove portion, and a projected portion formed in the concave portion. The auxiliary terminal is provided with an explosive portion exposed on the outer surface of the groove periphery and a secondary through hole, and abuts against part of the lead. The leads get through the first through hole, are bent along the right angle at the bottom of the groove, and are contained in the groove. The auxiliary terminal is press connected to be jogged with the projected portion on the insulation terminal plate through the second through hole.
