Claim 0:
1. A circuit-board holder comprising:
a first restraint configured to restrict a circuit board from moving in a direction orthogonal to an insertion direction of the circuit board, the circuit board being inserted to the circuit-board holder in a direction parallel to a surface of the circuit board;
a second restraint configured to restrict the circuit board from moving in a normal-line direction to the surface of the circuit board; and
a third restraint configured to restrict the circuit board from moving in the insertion direction of the circuit board when the circuit board has been inserted to a prescribed position,
wherein one end of the third restraint in the insertion direction of the circuit board is fixed,
wherein another end of the third restraint in the insertion direction of the circuit board is elastically deformable and displaceable in a normal-line direction to the surface of the circuit board,
wherein the third restraint includes an engagement portion at said another end of the third restraint, and
wherein the third restraint is engaged with a to-be-engaged portion of the circuit board using a snap fit,
wherein the second restraint includes:
a plurality of first surface restraints that contact and restrict a first surface of the circuit board at different positions in the insertion direction of the circuit board, and
a plurality of second surface restraints that contact and restrict a second surface of the circuit board at different positions in the insertion direction of the circuit board,
one first surface restraint positioned upstream from a most upstream second surface restraint positioned most upstream among the plurality of second surface restraints in the insertion direction of the circuit board, and
another first surface restraint positioned upstream from a second-most upstream second surface restrain in the insertion direction of the circuit board,

wherein the second-most upstream second surface restrain is positioned downstream from the most upstream second surface restraint and second most upstream among the plurality of second surface restraints in the insertion direction of the circuit board.
