Press-fit terminal and electronic device including press-fit terminal

A press-fit terminal for being press-fitted and deformed in an insertion hole of an attachment body and electrically connected to a surface conductor of the insertion hole by a reaction force caused by deformation, the press-fit terminal comprising:

• a bar part;
• and
• a deformation part provided at an end portion of the bar part and configured to be deformed in a deformation direction when inserted into the insertion hole, wherein
• the deformation part has a shape expanding at a part between a front end portion of the deformation part and the end portion of the bar part, and the deformation part includes:
• a recess provided between the front end portion of the deformation part and the end portion of the bar part, the recess being recessed in the deformation direction from a peripheral portion;
• a front boundary portion defining a boundary between the recess and a surface of the deformation part adjacent to the front end portion of the deformation part, the front boundary portion having a right angle or an obtuse angle with respect to the surface of the deformation part;
• and
• a rear boundary portion defining a boundary between the recess and the surface of the deformation part adjacent to the end portion of the bar part, the rear boundary portion having a curved surface shape.
