Disk device

A disk device comprising:

• a first substrate that includes a first pad;
• a second substrate that includes a second pad and is spaced apart from the first substrate;
• a holder located between the first substrate and the second substrate, the holder having
• a first end surface that faces the first substrate,
• a second end surface that faces the second substrate, and
• an outer surface that extends between the first end surface and the second end surface,
• the holder being provided with a groove dented from the outer surface in a direction and opening to the first end surface and the second end surface;
• and
• a lead attached to the holder, the lead including
• a first terminal that abuts on the first pad,
• a second terminal joined to the second pad, and
• a fourth part disposed in the groove between the first terminal and the second terminal, wherein
• the holder has an inner end surface at an end of the groove in the direction, the inner end surface extending straight between the first end surface and the second end surface.
