Provided are a heat exchanger and a refrigeration device with which the drainage performance above a cap member can be ensured while maintaining excellent adhesion between the cap member and header collecting pipe main bodies. This outdoor heat exchanger (20) is equipped with header collecting pipes (22, 23) that are connected to flat perforated pipes (21b) to which multiple heat transfer fins (21a) are joined, and the header collecting pipes (22, 23) are equipped with a header collecting pipe main body (50), and with baffles (60) serving as partition plates. The header collecting pipe main bodies (50) are arranged such that the longitudinal direction thereof is the vertical direction. The baffles (60) are provided as cap members closer to the inside than the upper end of the header collecting pipe main bodies (50), covering the upper side of the header collecting pipe main bodies (50). The header collecting pipe main bodies (50) have a pipe-end portion (53) that extends farther upward than the baffles (60) serving as cap members.
