Semiconductor storage device

A semiconductor storage device comprising:

• a board including a notch of which one end is open;
• an electronic component including a component body disposed in the notch and a lead protruding from the component body and connected to the board;
• and
• a holder disposed in the notch and supporting the component body, wherein
• the notch includes a first edge that extends along a first direction and a second edge that is separated from the first edge in a second direction crossing the first direction and extends along the first direction,
• the holder includes a first groove extending along the first direction and engaged with the first edge, and a second groove extending along the first direction and engaged with the second edge,
• each of the first groove and the second groove includes, in a cross section along the second direction and a third direction corresponding to a thickness direction of the board, a first portion whose width in the third direction is larger than a thickness of the board, a second portion whose width in the third direction is smaller than the thickness of the board, and a third portion disposed between the first portion and the second portion, the third portion having a width in the third direction that gradually decreases from the first portion toward the second portion, and
• the first groove and the second groove are each provided at the same level as the center of the electronic component in the thickness direction of the board.

A semiconductor storage device comprising:

• a board having a region with an opening;
• an electronic component including a component body disposed in the opening and a lead protruding from the component body and connected to the board;
• and
• a holder disposed in the opening and supporting the component body, wherein
• the region includes first and second edges on either side of the opening, the first and second edges extending along a first direction and separated from each other in a second direction crossing the first direction,
• the holder includes a holder body at least partially formed in an annular shape and into which the component body is inserted, a first engagement part extending along the first direction and engaged with the first edge, and a second engagement part extending along the first direction and engaged with the second edge, and
• the first engagement part and the second engagement part are each provided at the same level as the center of the electronic component in a thickness direction of the board.
