## Abstract

A method of manufacturing a solar cell module includes: placing a light reflection member across a gap between adjacent two solar cells set on a work table; and attaching the light reflection member to respective ends of the adjacent two solar cells, by thermocompression-bonding respective overlap regions of the light reflection member with the adjacent two solar cells using a compression bonding head that includes: a first thermocompression bonding portion and a second thermocompression bonding portion each having a contact surface that comes into contact with the light reflection member; and a non-thermocompression bonding portion interposed between the first thermocompression bonding portion and the second thermocompression bonding portion and not thermocompression-bonding the light reflection member.
