Solar cell module

A solar cell module including:

• a casing including a wall;
• a resin box attached to the casing, the box including a terminal accommodating part;
• a cable configured to connect an external part, an end part of the cable extending into the box;
• and
• a terminal fitting, accommodated in the terminal accommodating part, the terminal fitting connected to the cable and to an output conductor, wherein
• the wall of the casing has a first opening for attaching the box from an outer surface side of the casing,
• the terminal accommodating part includes a second opening provided in a wall surface of the terminal accommodating part facing the wall of the casing, the second opening being directly adjacent to the wall of the casing,
• the second opening faces an inner part of the casing through the first opening when the box is attached to the casing,
• a portion of the terminal accommodating part, surrounding the second opening and on a peripheral edge of the second opening, protrudes into the casing through the first opening such that the portion of the terminal accommodating part extends through and beyond the first opening and into an interior of the casing,
• the portion of the terminal accommodating part that extends into the interior of the casing defines an engaging member that is configured to deformingly engage a peripheral edge of the first opening, and
• a positioning pin is provided on a surface of the box that faces the outer surface side of the casing.
